I am looking forward to a picture of your new chick. Congratulations on the new baby. I do agree that a broody hen is the best incubator. I don't think that you will have any problems raising the chicks together. When chicks are this young they haven't established any kind of pecking order yet. So I think that you can add chicks together for several weeks and not have any problems. My family and I are wishing you and your family the best. Christina
