Thanks Fiefs20 and DBerryhill!
Last night I put the 6 young hens up on the roost after all the older girls where up there. There was a bit of pecking by the closest of the older group, but after I left, they settled down. When I got up this morning to let them out, everyone seemed content. So far, fingers crossed...

they seem to be doing okay. There has been a little pecking, which I'm okay with...lol, but they seem to be hanging in two separate groups so far today. I guess we will see how it goes if we get any of the storms they are saying we are due this afternoon and they are all going to be in the coop together during daylight hours. lol
Thanks again!
