In Maryland, any person who keeps or cares for chickens must register with the Maryland Department of Agriculture. A person must also register other kinds of poultry, including ducks, geese, turkeys, pigeons and doves. The registration program helps protect the Maryland domestic poultry industries from the spread of disease. The registration form can be found on the Maryland Department of Agriculture's website.
Read the Law: Md. Code Ann., Agriculture, § 3-804.
Counties and cities regulate the number of chickens that a person can raise on a specific piece of property. They may also regulate the size of the lot, the distance of the hen house or coop from neighbors and other conditions. For this reason, a person wishing to raise chickens must check the law in the county where he or she lives.
The following table shows information for Baltimore City and certain counties in Maryland:
You may not keep more than 5 chickens on one property, and no roosters. Chickens must have a "sturdy coop" and an attached, secure enclosure set back at least five feet from the property line.
