I have 1 Buff Rooster and 5 hens all 1 year of age. I noticed in the fall they were hens were losing feathers and thought they were molting. Through the winter I upped the protein however I noticed that on their backs and under the wings signs of pin feathers. Then I realized that this was from the Rooster over mating the girls. The egg production was pretty good throughout the winter 2-4 and sometimes 5 eggs a day. BUT today my husband went to the coop to check on the girls and noticed all but 1 was in the run. He scooted her out and she layed on the ground and wouldn't budge. She kept closing her eyes. I went out and noticed her comb, wattle, and skin very pale and cool to touch. We got 5 eggs today so she did lay. We separated from the flock because 1 of the hens started to peck at her. I took these pics can you please help me. I checked her body for lice and mites and I don't see signs, of black dots, or white eggs of shafts of feathers however this is my first flock. Those tiny black specs are the ends of her broken feather shafts.
