I need some advice. All my silkies go to their coop each night, except one. Louise paces by her run door, making lots of noise when the others go into the coop. Open the run door and she'll hop out, pecking bits of grass, not going anywhere. When I place her on the ladder, which we do each night, she'll go in. Any ideas why she won't go in? Any ideas how to get her to go in on her own?
