About a week ago one of my chickens went missing. We couldn't find her until last night I accidentally found her. She was stuck in a crack (kind of hard to explain how). I had hard time getting her out of there but when I did I saw that she couldn't walk. I thought that it's probably because she's really weak. I gave have her water and food and was hoping she would get better by next day. But today she still can't walk. She has a good appetite but I have to move her around because she can't on her own. Her left leg is really warm and seems to be a bit swollen while right one is cool temp. We had some bad weather. It didn't rain the whole week but it was below zero at night. And that place she was stuck in, is in shade so it didn't get much sun either. I'm worried that she maybe froze off her legs. Or maybe broke them since she was stuck in a very uncomfortable position where her legs were compressed. The pictures I provided is the position she's been standing, sleeping and slightly moving. My mom doesn't want to take her to vet she wants to put her down but I'm hoping there's something I can do to help her heal. Any idea what could be wrong with her and if I can do anything?
