So I've had to separate my 3 new 17-week old Speckled Sussex pullets from the 6 15-week old pullets that we've had since early March. A couple of the "old" girls were being a bit mean to the "new" girls, so I put up a screen in the coop for nighttime separation, and divided the run into two areas so they can see each other but not play chase. For those of you that have had to do this, about how long on average should I expect integrating the new birds into the flock take?
