That is concerning. I've seen a lot of pollen coming in, including some that is a strange beautiful dark blue. 2 days ago found a few drones already out walking the comb and capped drone brood (+worker brood). I'm feeding and looking to make splits pretty soon.
What I would say about your situation is that the bees are well-aware of it and will no doubt try to find a remedy. This might be best. Especially until you can determine whether she's begun laying eggs now, after a period of dormancy.
Obviously you could try to order another queen but this time of year will need to come from far away: CA or GA.
How about this idea: if one of us happens to find a capped queen cell in the next couple weeks, contact Mary to discuss replacing her queen and placing the cell into her hive...???
