Well that's the grossest thing I've had to do yet. My black Australorp was acting droopy so I brought her in for a check up. I felt a mass and thought she might be egg bound. After soaking her in a tub of warm Epsom salt water, I inspected and saw a large gaping wound, crawling with maggots! Uggggg. Anyway, I think I managed to get them all out and rinsed with hydrogen peroxide and betadine. There are conflicting instructions about antibiotic cream. What do you experts think? I trimmed her feathers around the vent which I think also had mite nests, then dusted with DE. I let her wander because I find when they are separated they get depressed. Any advice welcome.
