I wouldn't put it down =( Definitely try some physical therapy. Very gentle flexing. Even if it didn't get better it could still live. Definitely give it electrolytes though if anything. That is what my chiropractor told me to have when I was having issues.So....help! One of the chicks just hatched and it's hock is locked up. Like a chick I had once before with a slipped tendon but it seems pretty straight forward. Should I put the poor thing down now or do you think vitamins might help? Is there physical therapy I can do? I'll try to get a couple pics of it.
