I am just starting a multi-breed flock. Because I have to use different hatcheries, I will eventually have three batches of chicks in my large cardboard box brooders. I will have April, May and June flocks of chicks going out to the coop at different times. Each group will be about eight weeks old when they go out. All told there will be about 50 young birds being integrated over a period of 3 months. I only have one coop. Any suggestions on how to integrate them? Since they will all be less than 5 months old when the last ones get to the coop, will each group still require the lengthy look but don't touch approach? Any suggestions will be appreciated.
