My hen was limping. I read everything I could find about bumble foot. This is what I did. Soaked her feet in epsom salt This is what I got out of her foot. And this is how I wrapped her foot. My questions are... What causes this? Are there pre-warning signs? Do I do the procedure on every hen with a black dot on the bottom of her foot? What can it lead to? I read something about staff. Can I let then hen out with the rest or is it best to keep in a crate till totally healed? Thanks ahead of time for any feed back. I have been getting bits and pieces from many posts. I am enjoying my hens and everything I have learned from every one on this site.
