3 of my hens have really bad bumble feet. I’ve lost one already. We have been opening the abscess, pulling the corn, cleaning it with epson bath soak, hydrogen peroxide, antibiotic ointment and vet wrap. Two weeks in and it’s still showing up badly on two hens. The other one is not to bad. The floors are a stone dust, but last month it wasn’t draining very well with all the water we had. We have now changed the run and added a cover to keep the floors dry. Any suggestions on antibiotics? I’ve read about Tylan.
