Any idea what these bumps might be / suggest treatment? As a first pass I rinsed with hydrogen peroxide and then soaked for a min in diluted tea tree oil.
Where do you live? It it warm weather? I would look at possibly ant bites as a cause. Fowl pox somethimes affects the legs, but try to rule out bug bites first. Permethrin or permectrin diluted per label spray is very safe for treating a coop as well as the chicken.
Yes warm weather, east coast Florida (76deg today). We have three chickens, she is the only one with bumps. We do have quite alot of ants around the coop. I'll pick up some Permethrin today, thanks!
