I so should have brought a camera to the coop. I have the coop slit in 2, and just moved my 5 week olds back in there. They were 2 1/2 weeks when they lost their mother, and have been inside ever since. I have a heater in there. I have also been nursing my poor rooster, as he has been ousted by the new rooster. I decided to put him in with the chicks as he seems so unhappy kept in the house. When I went in to see how everyone was settling in, I found my old rooster on the perch with 2 chicks on him, 2 under his wing on one side, and 2 under his wing on the other side, then on pressed in to him. I could not believe my eyes.
