My BR hen had a lump between her toes on each foot, the size of half a marble. Not limping, happy other than starting to molt. I figured she had bumblefoot and got prepared for surgery. After soaking and scrubbing, some black stuff came out and it's dirt. Normal, gritty, 'clean' dirt. I got it all out, rinsed with iodine and sterile saline solution, packed with antibiotic ointment, put gauze on and taped up with vetrap. The hole looks all healed up, just healthy skin. But it's large enough to fit about two lentils, and it will just keep filling with dirt which seems unhealthy. Could this have been bumblefoot that healed itself? Could she have pecked at the kernel and cleaned it herself? Should i just leave it alone and let her have dirt there? Should I try cleaning it out well, drying it well, and gluing the hole shut with superglue or something similar? She seems a bit happier with the bandages on, but it is recently much colder here (25F low) and maybe it's nice to have warmer feet. My other hen had a spot in the center of her footpad that looked like bumblefoot as well, but it wasn't black, it was normal skin color like a callus. I pulled at it a bit with tweezers and got some of it off, but it was just like pulling off a callus and her foot isn't swollen. I'm not sure whether I could feel anything hard inside or not, it felt similar to her other foot. She's also molting and acting completely normal, active, and happy. Their roost is 16" high. I'm changing their ladder to get down into their run today, but they never use it, just 'thump' down. Maybe that's the problem. They are in a tractor house designed for 4 chickens, so they have plenty of room and get moved daily. Thanks!
