I'm new to raising chickens so chickens are still a wonderful mystical mystery to me. So I noticed that one of my RIR (at least I think they are RIR) had a funky butt lol so I took pictures and shes so sassay she tried to tell me to stop and I have the pictures to prove it. Of the actual butt deformation (or what I think is a deformation) I couldn't get the shot. She lays eggs just fine, but instead of her feathers pointing up they are kind of folded in. I will post my attempts of taking pictures of her butt XD
