I have a Welsummer hen with an injured leg. She's not very big - about 6 months or so (got her from another flock recently). Today she got caught in the fence (not sure how long she had been caught there, but probably more than 30-40 minutes) and after we freed her we noticed that she was limping. She can put weight on her right leg, and the foot is not curled, but it's noticeably crooked and she can only take 3-4 steps before she sits down on it. I've picked her up and felt it - the knee joint on the right feels a bit larger than the left, and there's definitely more play in the joint. (I can move her right foot side-to-side more degrees from the center than I can with her left foot.) I don't think anything is broken, and there are no obvious injuries like torn skin or a clear break. Could it be a dislocation? A slipped tendon? A torn ligament? What can I do for her? Splint it? Wrap it? Should I separate her from the other birds? (We have 1 other Welsummer and 2 buff orpingtons who are our original pair and are still a bit assertive with the Welsummers.) The other birds seem to be curious about her but not overtly aggressive. Help!
