I just moved mine into a new coop as well. First night, I had to place everyone in one of the "apartments". I sort of decided who went where after watching how they acted together. Tonight was the second night. When it was close to dark, everyone had picked an "apartment" to go into (I left two of the coops open to give them options until they fully integrate). Amazing enough, the way I had placed them last night was NOT the arrangement that they picked for tonight. I expect tomorrow night, the older ones will all go into one coop and the younger will stay in the second.
Anyway, I guess I'm saying as long as they are safe, let them work it out themselves. I needed to have all of mine in a coop because they are not safe outside. But after the first night of forcing, they were all tucked away tonight.
On a different note, the one that I have that tends to go broody won't stay away from the old coop. She flies over the fence to get back to the old coop to lay her egg. She's done that two days in a row, and then waits for me to lift her up to put her back in (now, if she could fly out shouldn't she be able to fly back in?). Her old coop is going to be dismantled in the next day or two, so soon she won't have anywhere to go. Funny how chickens become attached to a particular place.
Reading this helps my "1st night in coop" anxiety.....I'll let them work it out. I know they are safe but it's still nerve racking!!!
About your escapee...guess it's harder to teach an old hen new tricks??? Bless her little heart....never a full moment in the chicken world!!
