I have (4) 19 week olds and (2) chicks that are now 9 weeks old. I have had my run split in two by chicken wire for 3 weeks now where the two sets could see each other. The young chicks use a dog crate for a coop in their half of the run. I took the wire down yesterday afternoon to integrate the flock. I sat out there till night time with a squirt bottle and supervised the process, then put the chicks into their dog crate for the night. They are together again today. All the younger two are doing is running for cover and don't come out untill the older hens take a break under the coop. None of the older hens are very persistant, but my Polish roo is the worst at seeking the young ones out. I have tossed out scrath and hug leaves of kale to distract the older chicken, and that helps. But anytime the older hens get close to the young ones they peck them into hiding into the dog crate. I have two question: 1) When will the older chickens quit chasing the young chicks into the dog crate and contantly picking on them? I do not free range, they are locked in the run together. 2) Should I try putting the younger two in the big chicken coop tonight? I've read you wait till everyone is asleep, then place them on the roost with the older chickens. I am scared to lock them in the coop with the older chickens because they won't have any place to run away to. This is hard!
