We are new to chickens (chicks last April) and this is my first post. I did some searching on this,but it was mostly inconclusive. This is a Buff Orpington. She is 8 months old and seems to be happy. Can someone tell me what this is? Does it need treatment? This is the area below her ear that normally has no feathers already, and the other side of her head is normal, with a bit of loose, wrinkly skin where this side is bulging. It is not hot. It's kind of soft, but not too squishy. She doesn't mind if I touch it. thanks!!
