Hi Gbee
I have been learning to be very patient with queens. I would keep checking for queen cells before introducing your new queen. Would be sad to waste a Wayne's, or any queen for that matter, that still might be in the hive. Queens can be soo shy.... let me think here.... so if there aren't any eggs there might not be any queen cells...
Could be..maybe.. that she stopped laying for a bit. I do remember somewhere that the girls tell her when to lay, and when to slow down, or when to stop all together for awhile.
Is there any room for her to lay in this hive? Maybe that's why you're not finding eggs? a thought
I am still continually removing frames from the brood boxes of all my hives because the bees have overloaded the cells with nectar/honey, nectar bound hives, and I have yet to feed this year... I've had to keep replenishing the hives with new wax frames so she can continue to lay.
So, I talked my way thru this Gbee
I think I would recheck that hive and examine it very closely for eggs that were layed by a queen, on the bottom of the cells, and/or queen cups and cells for a week or two.
PS. This is why I like to mark my queens. I can find her right away.
