Everything is going good with the integration of my 6 week old chicks in the run with the two big girls....they are 31/2 months old....I had the babies in a "play pen" in the run for two weeks and let them out today....they get chased every so often by the big girls when they are in the way...but otherwise all is well. They do have access to their play pen through an opening too small for the big girls. Whey!!! made it through that hurdle!
