Re: How soon can you split a nuc/package
You should not have a problem splitting a package two months in. If you have two deeps with most of the frames drawn and coverwd with bees, no reason you could not make 2-3 nucs with them, especially if you will be adding a mated queen to each. Three frames of bees to each nuc and make sure you balance the resources too. May need to knock the donor hive back down to a single deep for a few weeks.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
