I have 9 female chickens, 6 golden comets and 3 black-sex linked chickens. All but one live perfect lives. The loner "Buttercup" is always away from the group just standing there...I know she's at the bottom of the pecking order. The other birds don't pick on her all the time but they give her a peck now and then when she is in their way (but they all get pecks once in a while). She does, however, get to eat and drink in peace. I don't know if you're familiar with it, but she is always fluffed up. She never has her feathers laying flat against her like the other hens. She looks like a football with legs. Why is this? She hides in the nest boxes (but as far as I know she doesn't lay or sit on eggs). Tonight, I went in to check on them and she was standing in the middle of the floor. I picked her up and put her on the lowest roost away from the other hens and she didn't move. Her legs literally made contact with the roost, she grabbed on, and stood there...didn't move or settle in or even sit down. She DOESN'T DO ANYTHING! Please help me. I want to make her happy or find a way to help her. By the way, she has been like this for as long as I can remember, lethargic and motionless. I put treats right in front of her face but she barely moves to touch them. Please please please help. Thank you.
