Re: Conditions for early splits w/purchased queens
I use nights consistantly above 40°F for my walkaway splits. Stronger is better, so I like three frames of bees, four if you can spare them. I also need to have emerged drones but not an issue for you.
Last year I started early with too few bees, we got cold and I lost all the brood I put with them. Terrible waste of resources and they did not make a queen. This year I am going to lock them in for a few days since my splits stay in the same yard.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
