Re: How much time do you have to transfer a frame of eggs from one hive to another?
Ok, the best way to transfer a frame is in a nuc with the bees. Second best would be to shake the bees and place in a nuc box with a warm wet sponge or towel in the bottom. Third best is to simply wrap the frame in a warm damp towel and try to keep it out of drafts. My understanding is that that will give you about a two hour window. Longest I have gone is an hour and in that case, all the brood emerged. Worst way is to place it on your car seat unwrapped with the ac blowing on it.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
