I just recently bought a group of coturnix quail (1 male, 2 female) and have noticed that one of the females has a small bald patch on the top of her head and a large red bald patch down the side of her neck and she also has a few broken feathers on her wings and tail. The male and other female look completely fine (happy and healthy). I was watching them for ages and didn't see pecking from any of them. Please help I am really worried.
