Hi---my 7 year old hen was limping a little bit a few days ago. She has had problems with leg mites this last winter, and usually I can just soak the leg and apply antibiotic ointment for a few days and it goes away. This time was a little different---the soles of her feet and her hocks were red, hot, and a little swollen. I brought her in to keep her on towels and sterile pads, and continued the soak-and-ointment treatment. She was standing and limping for two days, then staggering strangely for a day, and then yesterday she tipped over face-forward and hasn't been able to stand up since. It's very weird, her legs seem to go straight out behind her. The swelling and redness is going away, but she's not getting up. She's also very thin and ruffled up. She had a bad day yesterday, not eating or drinking, but she's taking water from a syringe today and eating well. I have her propped up on rolls of sterile pads so she doesn't just lay on her face. Does this sound like infectious synovitis? None of the other chicken are having any problems (yet), and there hasn't been any sneezing, etc. One chicken in another flock showed some lameness, but recovered after two days of soaking and is fine.
