Raising Chickens in Maine: Laws, Breeds, Climate

Maine is one of the most chicken-friendly states in the country, and the legal landscape got even friendlier in recent years. In November 2021, Maine voters approved a first-in-the-nation constitutional "Right to Food" amendment, declaring that all residents have a "natural, inherent and unalienable right to grow, raise, harvest, produce and consume the food of their own choosing." In 2025, the legislature followed up with Title 7, Section 219-D, which bars counties and municipalities from outright banning the keeping of hens on residential property. Cities can still set reasonable rules on flock size, setbacks, and coop placement, but a total ban is no longer permitted.

Maine's climate is the other half of the story. Winters are long and brutally cold, especially inland and in the north. January lows in Bangor average around 7F, with extended stretches in the single digits and overnight lows that regularly drop well below zero. Summers are short, mild, and humid, with July highs in the upper 70s to mid 80s along the coast and slightly warmer inland. Mud season in spring and ice storms in winter add extra challenges. Your breed choice and coop setup need to handle deep cold, heavy snow loads, and a robust cast of predators.

Are Backyard Chickens Legal in Maine?

Yes, statewide. Since 2025, Maine law (Title 7, Section 219-D) prohibits any Maine municipality from adopting an ordinance that bans the keeping of hens on residential property. Roosters are not protected under the statute and can still be banned locally. Cities retain authority to regulate flock size, coop setbacks, permits, and nuisance issues under their home rule powers.

In practice, most Maine cities allow 6 to 12 hens with modest setback requirements, and a few towns require an annual permit. Rural areas and unincorporated land generally have no flock size limits beyond standard nuisance rules.

Before getting chicks, check three things: your city or town's ordinances, any deed restrictions or homeowners' association rules on your property, and your zoning district. Even with the new state protections, HOAs can still ban chickens through private covenants, and individual cities can still set caps on flock size.

Maine Chicken Laws by City

Important: City and town ordinances change frequently, and Maine's legal landscape around chickens has been shifting since the Right to Food amendment and the 2025 statute. The information below was researched in May 2026 but may not reflect the latest rules. Always verify with your local code enforcement office before starting a flock. Links to official sources are provided where available.

◆Portland

Portland Code of Ordinances Chapter 5, Article V

Portland is one of the more permissive larger cities in New England. The city's permit requirement was repealed in 2017, and the rules have stayed essentially the same since.

• •Hens: Up to 6 female chickens per lot.
• •Roosters: Not allowed.
• •Permit: No permit required (repealed 2017).
• •Location: Henhouses may only be located in rear yards.
• •Enclosure: Chickens must be kept in a chicken pen during daylight hours and secured in a henhouse during non-daylight hours. Free-roaming is not allowed.
• •Other: Code addresses noise, odor, lighting, and waste storage. Eggs are for personal use only under the city code.

◆Lewiston

Lewiston Chicken Keeping Cheat Sheet (PDF)

Lewiston allows hens with a use permit on qualifying residential lots.

• •Hens: Up to 6 hens.
• •Roosters: Not permitted.
• •Permit: Use permit required from Planning and Code Enforcement.
• •Lot size: Minimum 15,000 square feet in eligible residential districts (Rural-Agricultural, Low-Density Residential, Suburban Residential, Medium Density Residential, and Neighborhood Conservation "A"), with a single-family detached dwelling.
• •Setbacks: Henhouses, fenced areas, and enclosures must be at least 20 feet from neighboring dwellings.
• •Location: Rear or side yard only, behind the principal structure.
• •Nuisance: Odors must not be perceptible at property lines; noise must not disturb neighbors.

◆Bangor

Bangor has historically restricted backyard chickens to its agricultural zones, which are located mostly on the outskirts of the city. Following the passage of Title 7 Section 219-D in 2025, the city's outright ban in non-agricultural residential areas is no longer enforceable, but specific updated rules may still be in development. Contact the Bangor Code Enforcement Office before getting chickens, since the city is in transition on this issue.

• •Hens: Historically restricted to agricultural zones. The 2025 state statute prohibits a complete ban on residential properties, so updated rules are likely.
• •Roosters: Generally not permitted in residential zones.
• •Setbacks: Contact Bangor Code Enforcement for current requirements.
• •Note: If you live in Bangor, call the Code Enforcement Office at (207) 992-4204 for the most current guidance before buying chicks.

◆South Portland

South Portland Code Chapter 3 Animals and Fowl (PDF)

South Portland adopted a backyard chicken ordinance allowing hens with a city permit.

• •Hens: Up to 6 chickens per lot.
• •Roosters: Not permitted.
• •Permit: Required. Annual fee of $25, with an additional one-time $25 fee for a chicken coop.
• •Enclosure: Chickens must be in a fenced enclosure during the day and secured in a coop at night.
• •Note: South Portland modeled much of its ordinance on Portland's earlier code and has reported very few enforcement issues since adoption.

◆Auburn

Auburn Code of Ordinances on Municode

Auburn ties flock size to lot size and requires coops in the rear yard.

• •Hens: Up to 4 domestic fowl on lots of at least 6,000 square feet, plus one additional bird per 2,000 additional square feet, up to a maximum of 10 birds on most residential lots. The 10-bird cap generally does not apply to lots in Residential Conservancy or R-1 Residential zones.
• •Roosters: Generally prohibited in residential areas.
• •Setbacks: Coops and fowl structures must be in the rear yard and at least 10 feet from rear and side lot lines.
• •Other: Keeping of poultry must comply with Auburn's noise, public health, and slaughtering ordinances.

◆Augusta

Augusta Code of Ordinances Chapter 119 Animals and Fowl

Augusta's code is less prescriptive than the Portland-area cities. The general rule is no public nuisance, with setback requirements for livestock structures.

• •Hens: Allowed, with no specific numeric cap in the code for most residential lots.
• •Roosters: Allowed in some zones; check current rules with Augusta Code Enforcement.
• •Setbacks: Structures for the enclosure of livestock, domestic animals, or reptiles may not be located within 20 feet of any residential dwelling on an adjacent lot.
• •Nuisance: Livestock may not be kept in the compact or built-up area of the city in a manner that constitutes a public nuisance.
• •Note: Because Augusta's code is more general, call the Augusta Code Enforcement Office at (207) 626-2365 to confirm requirements for your specific lot.

◆Biddeford

Biddeford Code of Ordinances Article III, Domesticated Chickens

Biddeford has one of the more detailed chicken ordinances in Maine, including specific rules on predator-protection lighting.

• •Hens: Up to 6 chickens per lot in most zones; up to 12 chickens per lot in the RF (Resource Farming) and SR-1 Suburban Residential zones.
• •Roosters: Not permitted (female chickens only).
• •Permit: Required from the Code Enforcement Office.
• •Setbacks: Henhouses and chicken pens must be in the rear yard with a 10-foot setback from all property lines. Corner lots without a rear yard may use a side yard if the 10-foot setback is met. No front yard placement.
• •Lighting: Predator-protection lighting must be a 90-degree cut-off luminaire on a motion detector.
• •Manure: No more than 3 cubic feet stored at once. Stored manure must be in a fully enclosed structure or properly maintained compost pile.
• •Commercial use: No selling of eggs or commercial breeding or fertilizer production.

Can You Sell Eggs in Maine?

Yes, and Maine is one of the easier states for small flock egg sales. The University of Maine Cooperative Extension's egg-selling guide and the Maine Department of Agriculture, Conservation and Forestry outline the requirements.

If you have fewer than 3,000 laying hens, you do not need a state egg license to sell at the farm, at farmers' markets, or directly to consumers. You do still need to follow labeling and handling rules:

• •Eggs must be stored and transported at 45F or below
• •Cartons must be labeled with the size and grade (minimum Grade B for retail outside the farm)
• •Cartons must include the packer's name, address, and ZIP code (a stamp or sticker is acceptable)
• •Cartons must state that refrigeration is required
• •If you reuse cartons, the USDA Shield must be obliterated
• •Cartons must be clean and odor-free

Note that some city ordinances (Portland and Biddeford, for example) prohibit selling eggs from chickens kept inside city limits, even though state law would otherwise allow it. Check your local code before selling, even at a roadside stand.

For sales to grocery stores, restaurants, or bakeries, or flocks over 3,000 hens, you'll need to register with the Maine Department of Agriculture and follow additional rules.

Best Chicken Breeds for Maine's Climate

Maine's climate is one of the toughest in the lower 48 for keeping chickens. Inland January lows regularly drop below zero, and extended cold snaps in the single digits are common from December through February. Coastal areas are milder but still see plenty of subzero nights. Summers are short and generally pleasant, so heat tolerance matters less than in southern states. What you need above all is extreme cold hardiness, and that means rose combs or pea combs (less surface area to lose to frostbite) and dense, fluffy plumage.

Best cold-hardy breeds for Maine:

• •Wyandotte: Rose comb resists frostbite, and the dense double-laced plumage insulates well against deep cold. One of the top choices for Maine. Lays 200-250 eggs per year.
• •Buff Orpington: Fluffy, deep feathering and a calm temperament make Orpingtons a Maine favorite. They handle subzero nights better than most breeds. Lays 200-280 eggs per year.
• •Plymouth Rock: Reliable, friendly, and built for cold New England winters. Lays 250-280 eggs per year. The Barred Rock variety is especially common on Maine homesteads.
• •Brahma: Large, heavily feathered birds with a small pea comb and feathered feet. Brahmas tolerate Maine's coldest stretches with no trouble.
• •Chantecler: Developed in Quebec specifically for harsh northern winters. The Chantecler has a small cushion comb and tight feathering that almost completely eliminates frostbite risk. If you can find them, they are arguably the best-suited breed for Maine. The breed is rare and listed by The Livestock Conservancy.
• •Australorp: Cold-hardy and an excellent layer. Black plumage absorbs warmth on sunny winter days, a small but real bonus in February.
• •Rhode Island Red: Tough, adaptable, and a workhorse layer. Single comb is more susceptible to frostbite than rose-comb breeds, but they handle Maine winters well with proper coop conditions.

Why combs matter:

A chicken's comb is the most frostbite-prone part of its body. In Maine, breeds with rose combs (Wyandotte), pea combs (Brahma, Ameraucana), or cushion combs (Chantecler) have a significant edge over single-comb breeds like Leghorns. If you want a single-comb breed in Maine, plan on petroleum jelly applications during cold snaps and tighter coop ventilation management.

Breeds to be cautious with:

• •Leghorns and other Mediterranean breeds: Large single combs are highly frostbite-prone in subzero Maine winters.
• •Light-bodied tropical breeds: Generally not a good fit. Their lower body mass and thin plumage struggle with extended cold.

Summer Care in Maine

Maine summers are short and relatively mild. July highs on the coast average in the upper 70s, with inland and southern Maine seeing low to mid 80s. Heat waves above 90F do happen, especially in August, but they're brief compared to states farther south. The main summer challenges in Maine are humidity, mosquitoes, and the occasional hot stretch.

Keeping your flock comfortable:

• •Shade. Even in mild summers, direct midday sun is uncomfortable. Tree cover or shade cloth over part of the run helps.
• •Fresh water daily. Refresh waterers at least once a day and twice during heat waves.
• •Ventilation. Maine coops are often built tight for winter. Make sure summer vents and windows can fully open on humid nights.
• •Mosquito management. Maine is famous for its mosquitoes (and black flies in late spring). Eliminate standing water around the coop, keep grass mowed, and consider a fan in the run. Heavy mosquito loads stress birds and can transmit fowl pox.
• •Heat stress. On the rare 90F+ days, watch for panting, drooping wings, and lethargy. Move stressed birds to shade and offer cool water.
• •Dust baths and pasture rotation. Provide a dust bath area for parasite control, and rotate the flock through different yard sections to avoid bare muddy patches.

For broader summer guidance, see our summer chicken care guide.

Winter Care in Maine

Winter is when Maine chicken keeping gets serious. From November through April, you'll deal with deep cold, heavy snow, ice, and frequent power-disrupting storms. Northern Maine routinely sees overnight lows below -20F. Even coastal southern Maine drops into the single digits regularly. This is where your coop design, breed selection, and prep work pay off.

Winter coop tips:

• •Ventilation over insulation. Counter-intuitive but critical. A sealed, humid coop causes frostbite faster than a dry, well-ventilated one. Keep vents open at the roofline year-round, above the roost so cold air doesn't blow directly on the birds. Moisture is the enemy.
• •Deep litter method. Start with 4-6 inches of pine shavings in the fall and add fresh layers through winter. The slow composting generates warmth and keeps the coop drier.
• •Heated waterers. Water freezes solid in hours during Maine winters. A heated base is not optional. Have a backup plan for power outages.
• •Skip the heat lamp. Heat lamps are the leading cause of coop fires. Cold-hardy breeds in a well-ventilated coop don't need supplemental heat down to about -20F. If you must add warmth during a deep cold snap, use a flat-panel radiant heater designed for poultry.
• •Snow load. Maine snow is heavy and wet, and lake-effect events north of Bangor can drop 2 feet at a time. Build your coop roof to local snow-load standards and clear it after major storms.
• •Frostbite prevention. Apply petroleum jelly to combs and wattles before deep cold nights, especially for single-comb breeds. Better yet, choose rose- or pea-comb breeds.
• •Extra calories at night. A handful of cracked corn before roosting helps birds generate body heat overnight.
• •Collect eggs often. Eggs freeze and crack within an hour or two on subzero days. Check nest boxes two to three times a day.
• •Wind protection. Maine's winter wind is brutal along the coast and across open inland fields. A windbreak on the windward side of the run makes a real difference.
• •Daylight drops below 9 hours. Egg production falls naturally. Some keepers add a timer-controlled coop light to extend daylight to 14 hours; optional.
• •Prep for ice storms. Maine winters reliably bring at least one significant ice storm. Stock extra feed, shavings, water containers, and a generator if you rely on electric waterers.

Common Predators in Maine

Maine's vast forests and mix of rural and suburban land mean predators are a constant concern. The predator list here is longer than in most states, and it includes one species (fisher cats) that gives many out-of-state keepers nightmares the first time they encounter one.

Suburban and small-town predators:

• •Raccoons: Common everywhere in Maine. They open simple latches and reach through chicken wire. Use 1/2-inch hardware cloth and carabiner clips on all latches.
• •Fisher cats (fishers): A large forest weasel and one of the most aggressive small predators in the Northeast. Agile climbers that squeeze through small gaps and will kill an entire flock in a single visit. A fully enclosed run with hardware cloth and a tightly built coop are essential.
• •Weasels and mink: Small enough to squeeze through 1-inch gaps and prone to surplus killing. Only 1/2-inch hardware cloth reliably stops them.
• •Hawks and eagles: Red-tailed, Cooper's, and sharp-shinned hawks are common statewide. Bald eagles along the coast and rivers can take adult chickens. Cover the run with netting or hardware cloth.
• •Owls: Great horned and barred owls hunt at night statewide. A fully enclosed coop with no gaps is critical.
• •Opossums and domestic dogs: Both common in southern Maine. Solid fencing and a locked coop handle them.

Rural and northern Maine predators:

• •Coyotes: Throughout the state, including suburbs. They dig under fences. Bury hardware cloth 12 inches deep or lay a 2-foot wire apron flat along the ground.
• •Red foxes and bobcats: Common statewide, especially in wooded areas. Lock the coop every evening without exception.
• •Canada lynx: Found in northern Maine forests, particularly Aroostook County. Rare encounters but possible if you're in lynx range.
• •Black bears: Maine has one of the largest black bear populations in the lower 48. Bears will tear apart a coop to reach feed or birds. Store feed in metal containers inside a locked outbuilding, never in the coop, and consider an electric perimeter wire.

General predator-proofing tips:

• •Lock the coop every night, no exceptions
• •Use hardware cloth on all openings, never chicken wire (chicken wire only keeps chickens in; it does not keep predators out)
• •Cover the run, top and sides, with hardware cloth or stout aviary netting
• •Bury hardware cloth or lay an apron 2 feet wide around the perimeter
• •Install an automatic coop door for reliable dawn-dusk closing
• •Store feed in metal containers, never in the coop
• •For rural and bear country: consider an electrified perimeter wire and motion-activated lights
• •Watch for tracks in fresh snow; Maine winters make predator scouting easier

FAQ

◆Do I need a permit to keep chickens in Maine?

It depends on your city. Lewiston, South Portland, and Biddeford require permits. Portland repealed its permit requirement in 2017. Augusta and many rural towns have no permit process at all. Rural land and unincorporated areas typically have no permit requirements beyond standard nuisance rules.

◆How many chickens can I have in Maine?

Most Maine cities cap residential flocks at 6 hens (Portland, Lewiston, South Portland), with Biddeford allowing up to 12 in certain rural-residential zones and Auburn scaling birds with lot size up to 10. Rural properties generally have no limit.

◆Does Maine's Right to Food amendment mean I can keep chickens anywhere?

Not quite, but it's the basis for stronger protections. The 2021 constitutional amendment established a right to grow, raise, harvest, produce, and consume your own food. In 2025, the Maine legislature followed up with Title 7, Section 219-D, which prohibits any county or municipality from banning hens on residential property. Cities can still set reasonable rules on flock size, setbacks, permits, and nuisance, and roosters are not protected under the statute. A pending case (Oliver v. City of Calais) is testing the broader reach of the Right to Food amendment in the courts.

◆Are roosters allowed in Maine cities?

Most Maine cities prohibit roosters in residential zones, including Portland, Lewiston, South Portland, and Biddeford. Augusta allows roosters in some zones. Rural properties with agricultural zoning generally allow them. Title 7, Section 219-D specifically excludes roosters from its protections, so cities can still ban them.

◆What's the best chicken breed for Maine?

Wyandottes, Brahmas, and Chanteclers are the top picks for Maine's extreme winters because of their small combs and dense feathering. Plymouth Rocks and Buff Orpingtons are excellent all-around choices that handle deep cold well and are friendly enough for families.

◆Can I sell eggs from my backyard flock in Maine?

Yes, with flocks under 3,000 hens you don't need a state license to sell at the farm, at farmers' markets, or directly to consumers. You must follow labeling rules (size, grade, packer info, refrigeration notice) and keep eggs at 45F or below. Some city ordinances (Portland, Biddeford) prohibit selling eggs from in-city flocks, so check your local code before listing eggs for sale.

◆Are fisher cats really that bad for chickens?

Yes. Fishers (often called "fisher cats" in New England despite not being cats) are one of the most aggressive small predators in Maine and will kill an entire flock in a single visit. They climb fences and squeeze through gaps as small as a few inches. A fully enclosed run with 1/2-inch hardware cloth on all sides and a tightly built coop with no gaps is the only reliable defense.

Maine is one of the best states in the country to keep backyard chickens. State law now protects your right to keep hens, the climate suits cold-hardy heritage breeds, and the local food culture is strong. The biggest challenges are picking the right breeds for deep winter, building a coop that handles snow loads and ice storms, and predator-proofing against everything from fisher cats to black bears. If you're new to chickens, start with our beginner's guide to raising backyard chickens for a full walkthrough.
