Just wondering what your systems are for producing quality drones and getting them into your mating yards? At full production I run around 1000 nucs in yards of approx 150. Three of my yards (450 nucs) are within easy flight of my breeding hives (30 of them all containing drone frames rotated in as required) so they should be fine. Just wondering whether I was a little down on drones in my other yards last season (my queen quality was excellent but my percentages were a bit all over the place). Any information or help would be much appreciated.
