Hi ya'll! Well, me and the family are REALLY getting into this chicken raising thing. We went to TSC on Saturday to get a few things like wood chips and feed for the rabbits and chickens we already have. Well, they had several brooders full of chicks. My youngest son, the one in my sig pic, decided he needed a new project. He makes his own money doing chores around the place. Each of the kids do. So, with his own money, he purchased three new baby chicks. I ain't too sure what kind they are. Two of them are black with some white tipped wing feathers it looks like. And, the other one is a mottled brown that almost looks like cammo. They are all three supposed to be pullets and egg layers when they grow up. My RIR's are close to 10wks old now I think and they are outside in their coop. When can I add the three new chickens to the flock? Do they need to be relatively the same size before they are introduced into it? I want to make sure they are all getting along before I put them together and I don't went the RIR's to hurt the newbies. Any advice ya'll?
