This is one of my Buff Orpington 16 week old chickens. I'm wondering if she might actually be a he? They were all supposed to be hens but we're not opposed to having a rooster so we will be keeping her either way. I have another Buff Orpington that is larger but this one has a bigger comb and wattles and the tail feathers are starting to look different. I haven't noticed any rooster personality. Sorry for the poor quality of the pictures but I was trying to zoom in for a better view. Thanks so much!
