Hi I have 4 little 2 day old chicks, being raised by a broody hen. Today, one of them managed to get into the tiny gap between the broody coop and run, and got stuck there. I found him, but his wings are splayed out, he is shaking violently, and he seems to be dragging one leg behind him. I am really worried about him because it was all going so well with them and they are all lovely and healthy and fluffy and I don't want him to die now! please help! should i leave him with his mum and let him warm up, or is there something i can do? because i really don't like not doing anything for him.
