I picked up some PR chicks Thursday and will be picking up some BO chicks this Thursday, so they will be a week difference in them. I built my brooder with a divider, and was wondering how long I need to keep the chicks separated? I was thinking of using the mesh divider so they can see and get used to each other, but for how long? A week? I did a search, but all I found had big age differences. Thanks for any advice.
