My hen has had what I believe is bumble foot, with a brown dot on the bottom of her foot for about a month. All of my other hens have these spots, but she is the only who limps. I thing it is caused by standing on the hardwire for too long so I try to get her out as much as possible. I left for a couple days and came back and now she is limping even worse then she has been for the last month and her whole foot is completely swollen. I feel if we do surgery it would only worsen it. What can I do???? She's in so much pain that, even though I will do anything to help her get better, if she gets worse I might have her put out of her misery.
