My BO has got some cracks in her feet like they are dry. One of the cracks in her feet started to bleed a little. My other hens don't have anything going on. Could it be leg mites? I have never had them before. How does it start? What are the first signs?I have washed her feet in a betadine wash then applied a antibiotic ointment to the feet. They look like they need some moisturizing. Any info is appreciated.
