Anyone have any experience with ISA Browns? I have one that has been a bit aggressive from the beginning (called her Meany), but now today I am wondering if 'she' is a 'he'. Still aggressive/bossy, but that of course could just be pecking order. 19 weeks old. Likes to hang around the chicken coop. Real friendly towards me. Nice straight comb. The comb is really the only thing that is making me question more than anything. Thoughts please? If 'she' is a 'he', he will have to go. Already have my designated roosters and he is not one of them. TIA!!
