Could this be Slipped Achilles Tendon in Hock Joint? I think this one is about 1-2 weeks old, just picked up a few days ago and trying to find information to help. Definitely causing some pain with too much movement so I have it in a small bin with a buddy and my baby quail. Eating and drinking but spending enough time on it's belly to cause a mat of feathers. No vet available. What can I do to try and help?
