Hi I am a newbie here and to owning chickens. We got 4 layers last week from a friend. They have been doing well and we are feeding them as natural a diet as possible. They cannot free range as we have dogs but we do let them out to wander each day for a period. Today one of them didn't want to scratch and do what they do when out but rather sat under a bush. She did eat breakfast but didn't want supper and has spent most of the day just sitting in her little hole she made and is now on her roost still looking sad! Can anyone guide me?
