Bumblefoot. One of my hens has it. I have 11 hens in a pretty big co...op/run. Their area is 8 foot wide by about 75 feet long. Within that is a brand new Amish custom shed 10x6 with gigantic windows. Their area is a combo of dirt, a little bit of gravel (under the shed and on one side for a foot or two), a sidewalk for about 20 feet. Their sleeping area is on plastic shelving, 1 2x4 wood roost and all but the 2x4 is deeply covered in horse show quality alfalfa/grass mix hay with more hay and deep bedding on the ground. We cut out the first bumble (vet wasn't available then so we did it ourselves) but hen still wasn't standing. This is the third day. So I checked again and found the other foot now has a swelling with the tell tale dot and on the first foot there is just starting a bottom swelling - the one we cut out on that foot was on top in between toes and yes we got the kernal out. She doesn't want to stand and doesn't want to eat but I've been feeding her a combo of canned cat food/Greek yogurt/Farina/electrolytes/mashed pellets. I've been giving her Tylan 200. With the additional bumble bumps on this one chicken (no other chicken is affected) I'm starting to worry there's something in the environment. I want to Lysol and lyme my yard. Other than that bizarre idea and not wanting to wait for cold weather to freeze the crap out what can I do? The vet did culture the first bumble and it tested positive for staph and e coli. I'm begging for input. Tomorrow morning I'm going to vet to cut out the rest of the bumbles.
