I believe those nucs came from Russells and they were stuffed. I have three sunkist queens I put in splits three weeks ago. I cannot say much past they seem to be laying machines. I thought I was so smart that I was finding them easily till it dawned on this dim bulb that all the bees in those colonies have carnie mothers and they stood out like lightbulbs! They are now on five frames and I hope they fill at least two deeps to winter. Dr Russell recommends that you winter them on three deeps and they will come into spring with a big population and make a pile of honey. Just like all farming, this is a next year business and I am waiting to see myself. He said on his website the other day he has sold 30 thousand queens so far this year. Must be someone to recoomend or pan his product out there.
