I have about 20 splits I made that will be queen right this week (should be) my attempt at using the mini matting nucs was a cat 5 failure so until I get a grasp on them I was considering just letting the newly mates queens that take lay for about a week then harvesting them and re introducing another virgin a few days later. Is this an acceptable method. Can it be sustainable for a few cycles without having to add many bees. These are five frame nucs in ten frame deep colonies.
