I'm doing a look but don't touch approach with my younger chicks. There is a 6wk gap between the 2 purchases. It's working well so far. They have been out in the mini coop (makeshift) I built for about 1 1/2wks now, yesterday we put all the hens except for 1 up, and kept the rooster out too. Kept them out interacting for a while, and then would bring 1 more out and let them interact for a while before repeating until all were out. My last one was a jerkoff and grabbed a chunk of feathers out of Quail. I did NOT put them into the big coop last night, and don't plan to until several rounds of this have been done. My younger chicks are appreciating being outside, but being where they can't be pecked. I tried regular introductions but the older were relentlessly pecking them, and I don't accept that (despite it maybe being "normal" chicken behavior), I can't have them pecking them until they bleed, and I certainly don't want them regularly ripping chunks of feathers out of younger chicks (or any for that matter).
