I have what I was told are two Black Australorp x Buff Orpington mix pullets. Today I found a weird appendage with little feathers growing out of it on one pullet's neck. I don't have a picture of it right now, but I will. is it normal for their breed cross? the person I got them from owned Black Australorps hens, a Buff Orpington rooster, a Barred Rock hen, several BB Red Old English Bantams and some guineas. The only ones in their separate areas were the broody hens with chicks. These pullets were the only ones this color in a batch of black chicks with their black Orpington mother. The one on the left has the appendage. The one on her right has a lot of red on her neck.. could that one be a boy instead of a girl? Pictures will be added asap.
