I have 3 - 4 week old chicks one of which I am going to give to a neighbor but I want to wait and see how they feather out before I decide which one to re-home. The neighbor has 3 RRs the same age. How soon do I need to decide which one - to limit the trouble when we combine the one with the 3 RRs? Or is it already going to be a process to combine?
