My BR chicks are three-weeks old right now. They are in a brooder in the house for another six weeks. My brother has some bantys that are around one-year-old that they are wondering if I want. I am wondering if I wait to get the bantys until my chicks are ready to go to the coop, will I able to put them into the coop at the same time without any problems. I hesitate to get the bantys now and put in the coop and let them establish "territory" thereby possibly creating a problem when I want to put the BR's in the coop.
