My BO rooster has a bad case of bumblefoot in one foot. I opened up the bottom of his foot but only got out some blood. I opened up the top of his foot on both sides between the toes because they were swollen and got out some white infected material on one side.I've been redressing the wound every other day but that doesn't seem to be curing the condition. His foot is still red and swollen although he walks fine. Is there an antibiotic I can give him? If so what and what dose? I don't think my vet handles chickens.Right now I'm concerned the infection will become systemic.
