We just got our first batch of chicks and aren't sure if they're all pullets or not. The store had 22 chicks so we bought them all, we like to jump in head first...lol So, I'm not sure if some of our BR aren't Roo's, anyone wanna take a shot? We have 6 BRs , all 3-4 weeks old. We aren't sure how old they are as they had started to feather at the store. These are the ones willing to set still for the camera... any ideas?
