Today the girls got to go outside the run. They were delighted as it was the first time in a while. While out and observing, I noticed that two of them have bare areas, right near the base of the tail on the back. Is this a) Rooster favoritism? or b) pecking due to inside and boredom after many days of snow/wind/rain Should I blu-kote them tomorrow, or just watch it? Both girls can cover most of the area with their wings but one is certainly a bit worse off than the other. I did not observe any other affected areas, or any other affected hens. How long until the feathers come back, if they don't get further bothered? Thanks!
