One of my hens (Greyjoy) got her foot caught in a gap between a roost and the wall. We found her hanging there, and unfortunately no idea how long. Couldn't have been more than a couple hours. As far as I can tell, she has no breaks, but her elbow and foot are swollen and she doesn't move any of that very much. I did see her move the elbow joint and hip, so I feel pretty good about her chances of recovery. I wrapped the joint in gauze and then used scotch tape to secure it in a middle position (not too bent, or too far outstretched). She's resting in the garage for a day or two and then I'll see how she is doing. Anything else I should do?
