I found my hen, Einstein, trying to sleep in a nest box, so I picked her up and put her on the roost. He went totally limp and sat on the floor. I picked her back up and tried again, but same results. It’s in the teens, so first thought was frostbite, but feet looked normal. No bumblefoot or anything odd. The only other thing I can think about is mereks, but I really hope it isn’t. For now she is in a nest box with another gal to keep her warm. Keeping her inside is not an option right now.
