Pale comb, stretches neck and screeching
Welcome to BYC. She looks very tired and the eyes are droopy. Does she have any diarrhea or blood in her poop? Does she look hunched or puffed up? Is she eating and drinking normally? I would consider worming her with Valbazen 1/2 ml given orally, and repeated in 10 days. The neck stretching and screaming noise could be signs of a respiratory disease possibly. Have you seen sneezing, nasal discharge, or any swelling around her eyelids? Can you look her skin over for any signs of tiny bugs or mites on her skin, especially near her vent? I would be tempted to treat her for possible coccidiosis with Corid if she is having diarrhea or hunched up. If it seems more like a respiratory infection, then I would get some Tylan 50 injectable, and give her 1/2 ml ORALLY twice a day for 5 days.
