Yesterday my chicken, April seemed fine. She was eating and drinking happily as ever, but when I woke up today i noticed she was lethargic and wouldn't eat or drink. Then when i went out later one of her eyes had bumps on it, it as closed and she won't open it. I then saw a bump on the inside of her mouth that was bleeding and a patch of feather missing from her back (don't know if this is relevant or if the other peck her), and i'm REALLY worried. I searched and it says there is no cure, is this true? And if so then is she going to die? Please anyone who knows anything reply as soon as possible.
