My white silkie pullet, age 6 months, has become limp in one leg, When sitting, the leg lays in front, and she seems to rest on her upper leg. When moving about, the foot drags behind her. We live in east TN, and have had a wet but mild winter. She has a warm dry coop and covered run, but is free to roam in a protected wooded area as well. She does get wet and muddy sometimes, and but seems not to care, as she is free to come in when she wants. Her feet were very dirty when I noticed the problem. Upon examination, the foot seems a bit swollen but not tender. The leg seems nontender. Th skin appears normal to me, without scaling, blisters or odors. I have brought her inside, given her a thorough bath and dried her well. She seems active though not walking, and does want to eat. Does this seems like bumble foot, an injury, a tendon problem, or something else? Do any of you have suggestions as how to best treat it? I do have Duramycin for oral use that I could give her.
