Dee -
I'm in PWC (right off Hoadly) and
this link will allow you to see the Domestic Fowl Overlay District for the County. Basically, it shows where poultry are allowed in the County if you live on a SR (semi-rural residential) zoned lot of 1 acre or more. If you are zoned agricultural, the laws are slightly different but the key take-aways are being zoned A or SR and having a lot size over 1 acre to be a legal Backyarder in the county.
The new zoning regulations allow the keeping of chickens, pigeons, doves and other domestic fowl on any A-1 zoned property of at least one acre. In addition, on properties zoned SR-1, SR-3 and SR-5 with a minimum of one acre by Special Use Permit and on parcels of 10 acres or larger.
The maximum number of fowl allowed is proportional to the lot size. One bird unit per acre is allowed for properties of 1 to less than 5 acres, three bird units per acre for properties of 5 to less than 10 acres. There is no limit on the number of bird units allowed on properties greater than 10 acres. A bird unit is:
10 chickens (though only one rooster per acre) or
6 ducks or
4 turkeys, geese or pea fowl or
1 ostrich or emu
20 pigeons, doves, or quail
