I'm going to be processing some of my older hens and the roo. I have replacements in the chick coop. I do have a small pen in the chicken run that I normally would put the pullets & roo into to introduce them in. But, with processing over half of my flock I'm really going to be upsetting the pecking order and I'm wondering if I should just go ahead and put the pullets and roo in with the rest right away before they re-establish pecking order?
