We found our favorite rooster in bad shape a few days ago and have been working hard to help him. Apparently he has "bumblefoot". I read the step-by-step presented for surgical procedure and will be following that as best I can.
David just found the other rooster and one of our 6 hens also has the spot on bottom of feet; thus we, suspect they all have it. We will be thoroughly cleaning the chicken house, roosting areas and chicken pen floor soon. Didn't know it was this contageous!
