Thanks everyone! for the pennsylvanians, we are in harrisburg, living right on the city line but our chickens are technically 'outside' the city. here's a picture of a few of our girls, the one in the front is the one we think looks more like a rooster...but we really have no idea. what do you think? we have 4 sexlinks and 2 that are part sexlink and part leghorn. I believe they are 16 or 17 weeks old. we got them from a farm north of here.
