I have seen several posts about mixing chicks/chickens of different ages, and that the older ones tend to pick on the younger ones. I have some chicks that are 6 weeks old and some that are 2 weeks old. I won't be able to put the 2-week old ones out in the coop/run for another 2-3 weeks anyway, but at that time my older ones will be 8-9 weeks old, and the newbies will be 4-5 weeks old. What's the best way to introduce them to minimize the damage? I understand that this will disrupt their pecking order, but I have heard/read that if I keep the newbies in a cage within the coop, the others will have time to get used to their presence before I actually "mix" them freely, and they might not really get violent. Is this true, and how long of a time frame do they probably need to get used to each other? Question Part 2: I have a friend with some fully grown hens, and some 6 week old chicks. They are about ready to start mixing them. Will the fully-grown hens really "pick on" the chicks? Or will the pecking order be pretty automatic considering the size/age differential?
