I have a RIR rooster and 2 hens that are one year old. I just incubated some of their eggs and have 7 chicks. At one week old I moved their brooder to the coop with the other chickens. Once a day I put the chickens in the run and let the chicks roam the coop for about 30 minutes. I then put them back in the brooder and let the others back in. The brooder is a large dog crate with cardboard all the way around except the top. It is on a 3 foot stand. What is the best way to integrate from this point so that the existing hens and rooster will accept them?
