Backyard Chicken Keeping
Many Chester County residents are interested in raising chickens in their backyard areas for a variety of reasons including the desire for fresh eggs and a natural food source. This etool provides guidance to municipalities interested in allowing for and regulating backyard chickens in traditionally residential zoning districts.
Adopting sound ordinance provisions can address the following issues encountered with backyard chickens:
- Noise: Chickens, and especially roosters, are vocal and can disturb neighbors.
- Roaming: Chickens will be destructive if allowed to roam. They will scratch and destroy flower beds and can cause traffic hazards if they enter roadways.
- Odors: Improper manure management can result in objectionable odors.
- Unsanitary conditions: Chicken manure can attract vermin and create vectors for disease transmission.
- Visual appearance: Chicken runs, coops and henhouses can be unsightly if not properly designed and maintained.
- Predation: Wild animals can attack and kill chickens, which have limited means of defense.
This eTool will not address all of the potential conditions that may arise in the course of keeping animals. Chickens may still cause disturbances to neighbors despite the use of the reasonable precautions that are included here.
How to Use this eTool
A backyard chicken ordinance should be adopted as an element of the residential accessory use provisions in the municipal zoning ordinance. See the model ordinance available on this webpage.
The characteristics of a good backyard chicken ordinance include the following elements.
- It recognizes the interest and popularity of chicken keeping in Chester County.
- The ordinance satisfies the needs of most groups, including those who have no interest in keeping chickens and may object to chickens in the neighborhood.
- It allows flexibility in unique situations.
- It allows input from the community during the creation of the ordinance.
- It takes into account the needs of the owner as well as the health of the flock.
- It is simple to understand and enforce.
Municipalities should consider the following additional issues:
- Most municipalities prohibit roosters, although hens can also be quite noisy.
- Some municipalities require owners to band the chickens’ legs, but this may not be practical.
- Slaughtering – should on-site slaughtering of chickens be regulated? If so, should it be permitted outdoors or should it only be conducted indoors?
- Chickens are not typically regulated as household pets and have different characteristics, so municipalities may need to review their definitions of household pets to exclude domesticated chickens.
- Municipalities distinguish henhouses and coops from chicken pens. Henhouses and coops are usually structures with solid walls and a roof, in which chickens typically remain during nighttime. Chicken pens are typically constructed of wire or mesh that provide access to the ground and provide chickens more freedom of movement. Chicken pens can improve the health of the flock.
