Thank you everyone. I am slowly integrating them into the group. Even the aggressive one seems to be accepting them. Momma kicks their buts if they get to close to the chicks. I am still being very careful however because she does not always pay attention to where all of them are and often gets separated from them. But in general they are doing well. She usually takes a circle around the yard with her chicks, has a dust bath and then returns to the run with the chicks. I then close them up. Everyone seems happy. I have included a photo of the family taking a dust bath.
