I've had such bad luck this year for keeping queens! To keep a long story short I bought 5 packages of bees, 3 queens (1 recent) and 2 queen cells from Purdue University . Caught 1 swarm and had 1 make it through the winter. I've lost 5-6 queens. The recent one is up and running. 1 Purdue queen doing well. 2 queens from the packages are doing ok. wintered hive queen doing good but made a split due to swarm cells. tonight I checked a few hives. Been a while since I checked the swarm. with my troubles I just left things alone for a bit. got in there and found capped and open brood but no eggs. Supercedure cells everywhere. What the heck! Again? I'm very careful when going through a hive. When I find the queen I gently put it in and usually end my inspection. This one hive still might have the queen but maybe something happened? I have opened and closed super cells. I'm just going to let them do their thing and hope for the best. It's a good thing I love bees.
