My 2yr old Goldline has not been well the last 2 days. She appears to be hunched up with her feathers puffed, her neck in, tail down and just standing there. She seems to drinking as normal, maybe more? She has her eyes closed. This morning when I opened the lid she was eating an egg which had a thin shell (dont know if it was hers) but the egg had not been layed in the nest box. Ive looked at her bottom, that seems clean and fine and she feels soft underneath. She is a terror for feather pecking, dont know if thats anything to do with it? Hope someone can give me an idea of what maybe wrong, she has always been a healthy chicken so far. I dont like seeing her like this Thanks.
