I have had the pullets in my run, seperated from the adults for a couple weeks now. I've been letting them mingle, supervised. The hens and the pullets got along wonderfully! I let them all sleep together for the first time and there were no problems at all 
I still don't fully trust my rooster around them so I keep him in his own separate part, while the hens and pullets get to mingle. I let him out with them this morning and he ignored them. So far so good, anyone else have stories/tips they want to share for introducing new flock members?

she still chases them a bit even now.. I was more worried about my rooster when I introduced ducklings, cause he was quite vocal when they first went outside into thier own pin, but again he totally ignored them when I turned them out to free range, but some of my hens didn't like them and they chase them away from the food.. I once again have some young pullets in thier own little pin around a baby coop and plan on letting them out to free range next week... I'm hoping once again all will go smoothly (kind of worried as this patch has what I think is a rooster in this batch...
