I’ve only had this hen for a few weeks. She just went broody a week ago, and before that she was spending a lot of time doing dust baths. I put DE in the dirt for her baths, because I was worried with all her bathing she might be itching. Now I’ve noticed this...missing feathers and there’s a red sore on her skin. She’s a skittish hen, and completely panics when someone tries to pick her up or touch her. She’s become even more skittish since going broody, plus she’s sitting on a few eggs that may be fertile. What should I do? My other hen looks fine, but I’m assuming I’ll need to treat her too because they sit side by side 24/7. My healthy hen has a 2 day old chick underneath her, and this is her first baby, so she’s equally skittish. Thanks for any help!
