One of my pullets started laying down yesterday in the coop. I let all the hens out so I could watch her a little easier. She walked and ran without seeming to squat or limp. She laid down for a few minutes and I examined her. Everything seemed fine except for her beak having saliva on it and her crown a little bloody from getting bullied like usual. Then she did something totally weird, she went into the woods, which she never does, for a little while ALONE. Today I again let her out and she laid at the edge of the woods. When I looked at her she was closing her eyes and grinding her beak together. We separated her and, if we can't comfort, will have her put down tomorrow afternoon.
