6 week old chick. My boyfriend was working on the coop with the chick's in the run, and tripped and accidentally hit the chick with his cast iron tool in the leg. (He is feeling really bad, so I'm trying not to be too irate at him for working near the chicks like that). I can see a shallow laceration on knee joint. I can't necessarily tell that the bone is broken, like I can't feel it move in a strange way, but the best way I could describe it is that the joint feels loose. And the chick is not moving her toes at all. She does move the leg from the hip joint.
I did my best to splint the entire leg, which I found difficult. I don't have a ton of hope for the chick, as from what I've read joint damage can be hard to come back from. I did read the tips on broken legs on this forum, but I'm wondering how long, with a chicken this age, should I wait to see if she needs to be euthanized? She isn't crying, just kind of laying there. I put a cloth under her leg so she doesn't have to hold it up. She is drinking and eating. How do I know if she is in pain?
Also I will attach a picture, maybe you can let me know if it looks like I could splint it differently or something. I tried to kind of match the angle to how she was holding her other leg while I had her on her back but...I really have no idea.
