Chickens, where are they allowed?

[Queensnative]

Hello everyone, I currently live in Windsor township, PA, and we are raising around 9 chickens and we are moving to Felton Borough, PA and I heard they do not allow chickens in the borough, but I searched online and came up with no results. We love our chickens a few have been with us for a few years now and don't want to lose them to crazy laws. So if any one has information for me that would be great and much appreciated...
