One of my 13 layer hens has Bumblefoot. The vet told me to give her water with 400mg/gal of Duramycin for 5 days on, followed by 5 days off and then repeat. Has anyone tried this and does it work well? More importantly, does it have any negative side effects? She doesn't like to be separated from the others and I'm thinking about treating the whole flock's water if there are no ill effects associated with the meds. Any thoughts? thanks!
