Last week, I removed the worst bumblefoot I have ever seen. It was in a hen that belonged to a co-worker. Like most cases, it started on the bottom of a foot. It had been there so long, it forked and had lumps poking up between the top of her toe webbings. If you notice the bottom of a foot with swelling, check it. Do not just let it go thinking it will get better. A small bumble foot is much easier to remove and easier to recover from that a large one.
