Hey thanks! I've been trying to breed certain chickens into my EEs for egg color. I agree with your sports medicine philosophy. As long as the chick is up and about, and not resting too much on the hock, or dragging itself around, I feel it's better for the chick to be moving around and trying to act normal, as much as it can. I've taken off the splint this morning, and I'm giving the leg a breather. Honestly the chick gets around just the same on the other leg whether he's wearing the brace or not. And the tendon refuses to stay in place. But at least the swelling hasn't gotten any worse. It's barely swollen at all. Oh, and thanks to your description, I finally figured out where the slipped tendon was. Inside of the knee= body side. Of course! Do you have a picture of your injured chick? We've named ours Professor Neutron.
