Have made splits taking Queens over to new splits and notching eggs in original hives using OTS method. Several original donor hives have made Q cups and are doing well. 2 Hives seem to take the cells down in a few days despite multiple attempts and new frames of notching eggs. Have waited 40 days after Q cells hatched in one of them with no eggs, no mated queens seen. Retried with more notched eggs... still no luck. I am notching the bottom third of cells containg eggs down to the foundation and then pulling down at a 45 degree angle to the next row of cells being sure not to harm the eggs. Should I be notching just hatched larvae instead of eggs? Notching eggs seemed to work fine in several other hives. If I can't get these two recalcitrant hives to make their own queens, will have to order some. I researched, read and ordered Q grafting supplies but this will take at least a month to get mated, laying queens. Any thoughts, suggestions appreciated. Many thanks.
