How long to keep pullets and hens separate

[Mrs. K]

With that much space, set up some roosts and some pallets to make hide outs in the run too. I think you are over the worst.

My littles have been free ranging with the older girls since they were 8 weeks, they are now 16 weeks and the old girls still never miss a chance to put one in line. So you see there really is no set time limit for integration. I've never tried integration in a run due to the reasons you're experiencing now. My only advice is to put some branches for the pullets to retreat onto since most serious bullying happens on the ground. But like everyone has said if you don't have enough room or food it isn't going to go well at all.Well shoot just saw you've got room so put up some branches and an extra feeder and ride it out.
