I have *4* 1 year old hens and *4* 5 week old chicks arrived today. I have read a ton of info on intergrating flocks but I can't find much info on integrating with such a big age difference. So, what is your experience? Do I really need to wait and maintain 2 coops until the chicks are 14-16 weeks old? Can I let them all start to mingle when the chicks are 8 or 9 weeks and then try to combine all in 1 coop by 12 weeks or so? Any and all advice is welcome and appreciated.
