I got 4 Barred Rock pullets from Tractor Supply on June 10th. So my guess is that they're the better part of 4 weeks old. As they started feathering, Alley is noticably lighter than the others. She also tends to chest bump and chase the others around the brooder. Last week, I noticed her comb started turning pink at the base. Now I'm starting to think my Alley is more of an Al. Do you guys think it's a cockerel, or just a pushy pullet?
