Sorry. The first is the hardest. But, if you have chickens you have to get use to it. She may have been egg bound. Probably why she was in her nest. I usually leave them alone if they are in the nest box at night. Usually means they are not feeling well. I have one now that is in her nest and will not last too much longer. She's hasn't been well for a while now. Old age, maybe. Sad, but that's the circle of life.
