Grafted the last Sunday in April and checked them this Friday....only to find nothing! I think the problem was I flipped the larva this time around or they dried out as it was quite hot out. I grafted in my truck with the AC on low just enough I didn't over heat myself!
Gonna try again in about a month, for now I am letting my splits raise their own queens.
On a positive note I am now up to 17 hives from 5 in march and all is going great!
