I'm getting the feeling they are all are 16 weeks. With it being winter they all refuse to leave the coop and are starting to fight with each other, not badly but enough for them to visibly be losing feathers I've been questioning their gender since theday I got them and going back and forth with some but I'm dying to know what they definitely are. A. B. C. D. E. This is D, I believe (front) and either A or E (back) it's hard to tell them apart This is A at 11 weeks. This is B at 11 weeks.
