Something that struck me when reading another post.
If I was to aim for 20% more queens than i needed to ensure enough were hatched out, is there anything i can do to increase the % return of queens to there nuc's once they've made there mating flight? or should 20% cover me for any loss....
Oh while I have yee...

When placing my nuc's in my apiary i was thinking of using 16' timber rails for fencing to make up collapsible stands. This would allow me put 5 nuc's at 3.2' apart is this far enough away from each other if I face them 1 forward 1 back etc?
