Help, one of my hens feet are incredibly swollen, it has been going on for a week, I looked for lesions and any black spots, nothing. she is lethargic, and can hardly walk now. I have been soaking and cleaning her feet daily, and dusting her feet. I have done the same with the rest of the girls too. I gutted the coop, scrubbed it down and dusted that also. I feel horrible. Her feet are so swollen. Any advice would be appreciated.
