I'm a little concerned about my dominique, her name is Twilight. She is acting fine, maybe a little less social but still peppy and keeps up with the other chickens, but she is losing feathers. Could she be molting? She was born in April I think, she so is around 9 months old, is that too young to molt? Also the winter seems to be an odd time to start molting, but I'm really not sure. I've been watching them and I know the other chickens aren't picking on her. Should I be concerned or is this normal chicken behavior?
