Swarms should lay in about two weeks if there is comb less if all is ideal. Swarms abscond on a regular basis. Thus the reason for queen includers. That is also why you leave them on for two weeks.
Virgin queens in a swarm are a gamble (what in beekeeping isn't?). If you lock in a virgin queen it's doomed. If you let her go on a mating flight she may not survive.
If you don't lock her in so she can go on a mating flight they may abscond.
It is nice to see you have been busy.

I didn't use excluders as these were cantalope size swarms and I hived them in four frames nuc w/ screens for vetilation and a finger sized hole for entrance. The best way i noticed is if it rains for a day after inserting into nuc. the rain makes the new home look good i guess.
