The lowest chicken in the pecking order of my little flock has been banished to her own end of the roost by the other 3 hens. They will not allow her to snuggle with them at night and it has been getting cold here. I recently bought her a friend for 50 cents at the local second hand store. I attached this friend with staples to the roost and the wall of the coop. And yes, she does snuggle up to her friend at night. I like to think that my lonely chicken is now warmer and happier.
