Hi, I am hoping someone can help with my chickens. We lost one last week (a red) and now I have another sick chicken with te same symptoms . She is very lethargic, and her comb seems to be turning black. She doesn't want to move - I moved her away from the other chickens (to keep her from being picked on) and she did drink a bit and she ate a little yogurt I left out for her, but she has not improved. Reading the other posts today, it seems like it could be mites, but I was hoping I could post some pictures and someone might be able to help me figure this out. Tomorrow I will dust all the chickens (19 hens total) thanks so much !
