I have a 3-month old Ameraucana pullet and I've just noticed recently that she's not very active. She used to bully some of the other chicks and ran around the place a lot but now she just sits quietly by herself with her eyes closed. Today I was looking around for her and found her sitting down with her face in a pipe. I picked her up and saw that there was white goop all around her vent and her feathers were stuck to it. There was a bit of brownish stuff dribbling out and it is very smelly. She looks sad and kind of hangs her head. I really hope there is some way to help her.
