I have a hen who is nearly a year old. She has been favoring one leg for several weeks now, holding it up when she stands. She'll put weight on it to walk, but only very quickly. Up until now, there's been no visible sign of injury or disease. The leg she's favoring looks like it *might* have a small bit of swelling at the joint, but otherwise looks completely normal. Just yesterday we noticed the tops of both ankles were slightly bloody—not actively bleeding, but looked like they might have been earlier in the day. It didn't look like a sore or lesion, but more like she had been pecking at them out of discomfort. Very light red and on the surface. We live on an old farm and she and our four other chickens free range. The only time they are cooped is at night. Her appetite is fine and her droppings look normal. Feathers, comb, and all other parts of her look normal as well. As far as I can tell, she's still laying. Last night, after we noticed the redness, we isolated her in a small coop to get her off her feet (chicken bed rest). We've added Duramycin from TSC to her water in case there is some sort of infection going on and are putting Vaseline on her feet to speed the healing. Since we cooped her she's been quiet and resting, but also moving around some—clearly not in distress. Can anyone tell me what might be going on? The only thing I've found so far that matches her symptoms in any way is Infectious Tenosynovitis, but she doesn't seem to match the severity of those symptoms. She manages to keep up with our other chickens most of the day. We don't have a vet in the area who sees chickens, so we're kind of on our own. Any thoughts and ideas would be appreciated—we're wrapping up our second year as chicken people, so we're new to this! Thanks.
