Re: Options for a queenless nuc
I think you have 2 good options.
1. Give the nuc a frame of mostly eggs and very youngest larva. Make sure there's eggs on it, this gives the bees some time to decide what to do with them. Taking eggs does not set them back so much as no time or resources have been invested in feeding larva. Sealed brood is not needed, you just need some eggs in that nuc hive so they can make a queen. Shake or brush the bees off it back into their own hive before giving the frame to the nuc hive. The nuc hive should have plenty of bees in it to care for it and you don't want to set the package hive back any by taking away bees as well as the frame with eggs/youngest larva.
2. Combine by laying sheet of newspaper over the nuc hive, and put the package hive on top of that. I find combines work better when the queen right hive is moved and placed on top of the queen-less hive.
Make your choice which to do, and enjoy your trip out of town and check on them upon your return.
Live life with gusto, having no regrets, being thankful every day, and cherish each moment as it happens.
