Hello, this is my first post on BYC. I'm sorry if I'm not posting in the right forum. I joined because I think one of my hens is sick and I want to help her. This is Frannie. She has been acting weird the last couple of weeks- walking very slowly, not wanting to really eat or drink, and she's been sticking close to me- like she's asking for help. Her eyes look tired and sickly. And her feathers, on the top of her head and neck, seem sparse and thin. Please see the photos. Does anyone have any suggestions for what I can do? All of my other chickens (approx 35 in the flock) are healthy and are not acting this way.
