I have 1 month old baby chicks, and something as small as a mouse (b/c where it got into the brooder) killed one and another is injured. She can get up, but is laying kind of crashed over on one side in a weird position and shivering. I've set up a separate brooder for her, but wonder if there's something else I could do for her. She has maybe a small bite with a tiny bit of blood on her back, but nothing else I can see. Any help is greatly appreactiated!
