Today I was cleaning off the feathers around my chickens vent because there was poop stuck on them. Then I noticed small brownish colored mites crawling around her vent. I checked my other chickens and two others had noticeable mites but I sifted Diatomaceous Earth through all of their feathers just to be safe. I am planning on doing this a few times a day for a few days. I am going to clean out their entire coop and I am getting more DE today. Any tips on how I should disinfect the coop and treat my chickens will be very helpful. Also, can mites affect people? I had her sitting on my lap before I realized she had mites.
