That many queens will burn out quite a bunch of drones! I commonly have quite a few dragon flies but I very rarely have fail to return mated. Everything I have read seems to suggest I have the prime requisites for a drone congregation area very, very close, so the virgins dont have to risk a long search. The only other kept bees are about 3 miles away; no ferals here that anyone knows of.I forgot to mention that I will be checking to see how many of the Queen's got mated and came back laying on the 1st round tomorrow, then I will check every Friday for each consecutive round.
