I have a hive that has been under performing lately. They have two deeps brood chambers (mostly plugged up with honey), but have made no progress on a honey super in about 3 weeks. It was a split in mid may and they raised their own queen back then. This weekend I checked the hive and could not find any eggs anywhere, just older sealed and unsealed brood. So I pit in a frame with lots and lots of eggs. I went and checked on them today and about 1/2 the eggs in that frame have hatched, but there is not evidence of any queen cells started. Under what circumstances would this happen? I am thinking perhaps there is a queen in there, she just stopped laying. I will give them a few more days and check again. What do I do if I find no eggs again?
