I know that its been talked about already, but I'm going to bring it up again. I put my older set of chicks into the coop last week, and the younger set yesterday. They were all in the same brooder up til then and did fine together. But today I went in the coop and the younger set are all crowded into one corner. The coop is heated to 70 and I have a lamp under which it's 90. I noticed the older ones pecking them any time they came out of that corner. I'm worried that they wont be able to get to the water or food, so I took some chicken wire and trapped all the older ones in that corner so now the younger ones have free range of the coop. I figure maybe I'll leave it like that for a bit to teach the older ones a lesson. What should I do?
