My girl is 2 with 10 other ladies. They have 18 ft of roost.40x20 run and 16x20 coop. It has been 100 here with high humidity. Miserable. She is loosing feathers on her chest and generally all over but on her skin she has dry red patches. I have not seen anything on the others. I thought molting til I saw the red spots. I have permithian liquid. Should I dip them?
