Need help with what I assume are mites… I have a flock of 15 eight month old hens and one rooster, all who are losing feathers around their rear and back except the roo… This is the worst one and looks like she has an open wound. Is this from mites or something else? We are first time chicken keepers so this is all very new to me. We use a deep trench method for our open air coop, and have never had bug issues before. My husband noted that the hen had little black bugs on her while this picture was taken. Would love any advice!
*Editing to add photo of the rear of one of my hens! I would say over half of my flock looks like this
