I have a hen that I got around Jan 1. She came w/ 2 others. I have treated all 3 for external mites. I have used both DE and the Poultry Dust to treat mites. 2 of the 3 seem to be ok. But this one hen doesn't seem to be getting better. I went away for 4 days this past weekend and this morning when I went to let them out I checked them and she has red irritated skin on her underside and near her vent area. Prior to me going away she appeared to be doing better. But now it seems worse. While I was away my husband was taking care of the chickens. He basically left them in the whole time I was gone as he didn't want to have to bother w/ letting these 3 in and out as I have them isolated from my others. Her skin is real red and almost seems dry too. I just put another treatment of Poultry Dust/Powder on her. What else should I do? I was going to let these 3 in w/ my other birds beginning of Feb, but now I am somewhat hesitant because of the way her skin looks (thinking it might be mites/lice, etc. and don't want to have the others get it). Besides the powder what else can I do? The other 2 appear to be fine, no irritated skin or missing feathers. So am wondering if it truly is mites/lice. I will try to get pictures and post them.
