My son has 8 11 week old chicks and 28 9 week olds. We just graduated the 11 week olds to the chicken coop last week and the others are in 2 separate pens in our garage. It is getting hot and crowded for them so we want to introduce the 28 younger ones to the 8 older ones. This afternoon we tried putting 6 younger ones in the coop for a trial run, but the rooster is keeping them away from the feed and water and the dominant pullet pecks when given an opportunity. The rooster is actually doing a good job of fending off the bossy pullet. Should we forge ahead with the other 22 or try something different?
