I have a BO who I was debating whether she was a hen or roo... she really looks like a hen now and acts like one except every so often. 5ish months old and no differences in plumage etc, no crowing, stuff like that. She can be aggressive towards me though... acting sort of roo-like. Her comb is big enough that it's starting to flop over and her wattles are pretty big too. I have 4 hens and got 3 eggs the other day, so who knows... Ideas? Comments?
