Around mid July I will probably doing the post main flow split. We have some nasty bees in the area so to avoid local drone contamination I was thinking about using a couple drone frames in a couple of my larger honey producing colonies and then grafting from my absolute top colony gentleness and production. Any thoughts on this? I was considering once the frame gets laid up hitting it with oav and then another time right before the cells get capped. I’ve read to do the drone frame 40 days before? I’m thinking since mine is not drawn out about 45-50 would be better. If July 15 is target for splitting I guess I’d have to put the drone frames in June 1 and graft queens July 1 for un matted introduction July 18th. Giving three days from split to remove emergency cells. I plan to have ~20 splits. Does my timeline seem right?
