Went through all mine yesterday .. didn;'t start until 5pm so the boxes were prettty full of bees. Put more supers on ... Only one queen cell .. found it in one of the colonies headed up by one of Ceri's queens from the year before last ... classic supercedure cell... right in the middle of a frame, lovely long cell and sealed up. Checked all the frames thoroughly and definitely only the one cell - she was laying like a train last time I looked and almost wall to wall brood but the brood was very patchy today, some day or two old larvae and a few eggs. Couldn't find the queen but I must admit the hive was stuffed full of bees and I figured, as there was only the one cell, I'd best let them get on with it and closed them up.
Knowing my luck they will swarm when I'm at work tomorrow ... but without a lot of searching it was worth the risk - I needed to get through the rest of the colonies and this was the first hive inspected. Probably a mistake !
Plenty of nectar going into to all the colonies and a lot of capped frames.
