I agree with the lots of room to run and places to hide. At the farm where my breeding flocks are, we let the chickens not in breeding pens have free run of the 10 acres. They do tend to stay within an acre of where they sleep & eat. The roosters all get along for the most part. The young ones learn to stay away from the big boys and some of the pullets/hens. We recently processed the extra cockerels both Pita Pinta from my breeding program and the mixes that hatched under broody hens at the farm. We processed 20 of them and my friend says that it is much quieter at the farm these days! We thought that we had all of them but as soon as we cleaned up the processing area, out popped 3 or 4 who were smart enough to hide! In addition to the cockerels both mixes and those that are still possible breeders, we have 4 roosters that are 2-4 yr old. They all have their own territory and their own group of ladies that they oversee. I love watching the flock dynamics!
