One of my hens (1 year old Red Sex Link) has a problem with one of her feet. It started over a month ago. I noticed a bit of swelling between her toes a few days before she became quite lame on the foot and there is heat. I could not find any obvious injury. I wondered if it might be bumblefoot. I still dont know that it isnt. I started by soaking her foot in Epsom salt and Betadine then wrapping her with Animalintex (a poulticing product made for horses, primarily, boric acid) and Vetrap (cut into narrow strips). I did this for a couple of weeks. I also tried adding Polysporin. The best results seem to come from the Animalintex alone re-applied as a cold, wet poultice every 12 hours. I was able to leave her foot unwrapped about 10 days ago. But the swelling has returned over the last couple of days and this morning, she is lame again, with heat. She has carried on with all her chicken things throughout laying eggs, foraging and roosting with the other hens, running, dust bathing. Completely normal except for the foot. I dont have access to an avian vet but my large animal vet would likely provide me with meds if I could present a compelling case. Anybody have any ideas? Pictures follow:
