I too noticed the bumblefoot when I noticed one of my hens had swelling between her toes a couple days ago. So I did some research and was able to perform the surgery tonight. Her one foot was horrible. The infection was on both the upper and underside of her foot. I think I got all the infection out. Unfortunately her other foot had bumblefoot as well only it wasn't as bad. So she now has two wrapped up feet. She still wanted to perch on the roost tonight though even though I tried putting her inside the house I keep the babies in. So since everyone was sleeping and easy to catch, I decided to check the rest of my girls. Turns out two more had bumble foot.

The other two only had it on one foot each. One looked like the foot 'might' have something starting but I cleaned that foot as well and put some cream on the surface. I didn't want to go digging for nothing yet. Once I got the scab off my one girl's foot, there really wasn't anything else inside. I hope not anyways. I went digging a little and it just seemed like foot meat. She was bleeding a lot and no puss or infection was coming out. I put triple antibiotic ointment on each foot and wrapped them all up. Fingers crossed they all heal without an issue. I really don't understand why 3 out of 9 hens have bumblefoot. They get to free range in our backyard every day and aren't locked in a pen. They sleep in their coop but don't hang out in there. I do the deep litter method and clean it every couple months, it really doesn't seem to need it more than that, plus they don't really hang out in there. They even (choose to) go out during rainy or snowy weather. We did have the roosts up kind of high so we put a ladder type roost in today and hopefully they don't jump from the top one all the way to the bottom. I hate when my girls are sick. :'(
