So I assumed she is dead in the cell and gave this nuc a new comb with fresh eggs. I came back to check this nuc in about 3 days and found one Supersedure Cell (capped) of a very nice size (long in the middle of the comb).
I reported this on the Bio Bees forum two days ago and Bernhard (bio bees respected member) suggested I look it up today and see if the Queen is still in the cell or, as it can sometimes happen, the cell cap can close itself down after the Queen gets out looking as if the cell is still occupied.
So this is what I've found;
I opened this cell very gently with a tip of the knife making sure not to touch the Queen. I could see her head and she was not moving. She was dead :(
I will now leave all hive in peace and not inspect until the 22nd of June when the urban beekeeping group Mykorrhiza Malmoe is to come and visit my apiary to get insight into Top Bar Beekeeping
