Strange problems with some queens this year. TBH it started last year. Multiple supesedures of queens. One is on to its 3rd queen this year. Lay 2 frames of brood then get replaced. First Q looked lovely 

I could have done Mick, but with the EFB threat in my area decided it was wiser to not move any colonies, just in case. Next year a mate of mine is growing 5 acres of the stuff.....so probably wander along there
