Interesting class, hope the rooster gets better.Crazy humidity, isn't it?
U of KY uses a CEH ointment to treat bumblefoot in raptors.
All I could get before was a Calendula cream and extracts of Echinacea and Hypericum. They didn't mix well because it was like trying to mix oil and water. I did use it successfully on 3 other birds in the past but the cream is now expired.
If daily soaking in Epsom salts and the herb treatment doesn't help in 4 or 5 days, I may have to break down and take him to the vet. He's my most valuable rooster since he is not from my flock's gene pool.
I just want it cured before the infection gets into his bone.
