Thanks to all of you who replied. I feel much better. I have placed her on the higher roost a few times, but I worry that the jostling that goes on will unseat her, so now I leave her to fend. I have named her Thumbalina. She is sweet and follows me around. I have taken her to the garden with me...
I have a 5 1/2 week old barred rock who is about 1/3 the size of her sisters. Her feathers are very thin almost as if she is molting. She has a lot of spunk and keeps up with the others though she cannot fly to the high roost like the others. Any ideas?
