Yes, backyard chickens are legal in Massachusetts, but compliance with state and local ordinances is mandatory. The Massachusetts Department of Agricultural Resources (MDAR) permits small-scale poultry keeping under specific guidelines, though municipal bylaws may impose stricter limits. As of 2024, no statewide ban exists, but cities like Boston and Cambridge enforce additional restrictions, including flock size caps and coop setback requirements. Violations may result in fines or confiscation, particularly in residential zones.
Key Regulations for Keeping Backyard Chickens in Massachusetts
- Flock Size Limits: MDAR recommends no more than 12 hens per household, excluding roosters, which are prohibited in most residential areas. Municipalities like Worcester and Springfield may cap flocks at 6–8 birds.
- Coop and Run Specifications: Structures must be predator-proof, well-ventilated, and located at least 20–50 feet from neighboring dwellings, depending on local zoning codes. The MDAR’s 2023 Small-Scale Poultry Guidelines mandate a minimum of 4 sq. ft. per bird in outdoor runs.
- Permit and Inspection Requirements: Some towns, including Newton and Brookline, require permits for backyard flocks, with annual inspections for health and sanitation compliance. Failure to register may void liability protections under state nuisance laws.
Local health boards retain authority to amend these rules, with several municipalities (e.g., Somerville) considering 2026 ordinances to limit flock sizes further. Consult the MDAR’s Poultry Resources and your town’s Zoning Bylaws for jurisdiction-specific updates. Non-compliance risks enforcement under the Massachusetts Sanitary Code (105 CMR 410).
