Today while I was giving my 3 week old chicks some time out in their outside run to start acclimating them to outside, I accidentally tripped over a group of them that swarmed my feet and started pecking my bare toes. I crushed one when I fell and it died instantly, and now another has turned up several hours later that seems to be in obvious distress. I am not sure if I hurt this one or what, but it is panting a little, and just sort of 'off'. We put it in a small 'emergency' brooder by itself. I was feeling it over, and don't see any blood or wounds, its legs and wings work fine and it can see and walk around ok. However, when I was gently feeling its body, it seemed like half the ribcage sort of collapsed inwards under any pressure. I felt a normal chick and it is definitely not the same. I am assuming it is broken. I can't tell how badly; I don't want to touch it more and cause the poor little guy any extra pain. I wanted my husband to put it down so it won't suffer, but he can't bring himself to euthanize such a cute little thing. Neither can I. He wants to see if we can save it, though I don't think it can be done. It is now standing up normally in the brooder and chirping, moving around some. What are the chances of a chick surviving anything like this? Is there anything I can do to help it out, or is it just a 'wait and see' sort of situation?
