An update. Elvis has died. She was out in the run this am, hiding under a board lean-to. Kinda just hiding out. 4hours later I found her dead next to the water in the run. I don't know where she slept last night, I had put a fresh layer of pine chips on the floor of the coop and some lean-to boards in case she slept on the floor. Didn't really look like she had though. I wish I would've brought her into the garage a few nights earlier. I don't know what it really was; sick, her extreme moult, recent cold snap, excessive pecking or a combination of all. I will closely monitor the remaining 6 hens. Does giving BOSS or mealworms,in moderation, increase the protein? I want to increase the protein, to help with the cold and molt, but don't want to deprive them of other nutrients
