Packages, and swarms, can be funny. I've had packages where the queen didn't start laying for several weeks after the bees were hive. Partly I think because the workers were fill the combs with nectar as fast as they could build the combs.
I've also had packages, like the 2 this year, where the bees were drawing comb (foundationless) and the queen had started laying eggs in comb that had hardly been started. 1 frames had the entire 1st row comb on the starter strip full of eggs. Now those are go getter queens. I like queens that will begin laying eggs in combs before the cells are complete.
