I found one of my young hens with skinned open wounds on her back and under her wing. Full of maggots. The attack must have happened when they were out yesterday, as they were in the run all day today. I’ve isolated her indoors and cleaned it with peroxide twice, and I’m about to go pack it with neosporin and bag balm. Any other tips? Should I try sugar/coconut oil/Vaseline? I’ve read conflicting info about all 3.
