For the last two months I've been letting my chicks I got in mid march run the yard with my one year olds, it's not going well. They remain in their individual groups of three and when they do come in contact with each other it's always the older ones pecking the young ones. The only time the young ones can come anywhere near the older ones is if the older ones are occupied with some treats I threw out in the grass. My biggest concern was I'm running out of time for them to get along in the older hens coop before the younger ones start laying eggs in their temporary dog kennel. Enter biggest concern, I found an egg on the floor while cleaning out the dog kennel! Should I just roll the dice, put them all in the big coop and hope I don't wake up to a dead chicken? Will they just work things out on their own? Help!
