Thank you for your input!
Right now I have the little ones in a half xpen (2x4') in one corner of the coop. I blocked off one 2' stretch at the corner end with cardboard so that they have half their space where no hen can stick her head in and bother them. That is also where I put their feed, grit and water. Everyone is doing fine with this arrangement.
But now it's getting hot and the coop will be too warm to keep them comfortable. Also, I really want the chicks to have time outside.
I just this morning rigged up another halfed xpen in one shady corner of the run for them where I will put them later when it warms up. I am just not comfortable with them freeranging yet, but would like for them to be on the meadow sometime, where they can hunt for bugs and scratch around. I could set up yet another xpen, full size and cover it with chicken wire, I guess. Would have to be supervised, but my big girls are only out when someone and the dog are there to watch, too, so I guess that could be ok.
I just thought if I had a small coop/run set up for them they could be out more and I wouldn't have to catch and move them around so much...
But I think you are all right, I just need to focus on integrating them. I have the jitters! These two little ones are my favorites, now (of course! always the babies...), a gorgeous SFH millefleur pullet and a blue-brown-white crested SFH cockerel, who I got to replace my two failed original roosters.
They have been in their little pen in the coop for three weeks now. Next step would be to rig their pen so only they can enter, but how do I find out the right size opening? Loch everone out of the coop, open the pen, adjust to what I think is the right size and throw treats in there to see if they will fit? Should I shoo them to practice running to safety into their pen? Also, the way the pen is set up in the coop now, it forms a dead end in one spot. I will have to block off a couple of nest boxes to eliminate that - but that would leave me with just two for 12 hens...? Though, they only use two right now, the ones at the far ends -
one of which would be blocked...
