Last Saturday, for the first time ever, I made a split from one of my hives. I found 3 frames in the brood nest with capped swarm cells of undetermined age (all I could tell is that they were fully built queen cells, not queen cups). I took all three of those frames out (with the bees still on them) and put them into a 5-frame nuc with a full frame of capped honey and an empty frame. I also put a hive top feeder on the nuc and gave them some sugar syrup. As of yesterday (Wednesday, 4 days later) the nuc was still alive - I peeked under the lid and the brood frames were covered with bees. I saw very few bees coming or going - one every few minutes or so. Assuming I didn't carry the queen over from the mother hive (which I don't think I did), how long should I wait before checking whether they have a mated queen (i.e. look for eggs)? Should I do any inspections in the meantime or just refill their feeder with syrup and leave them alone otherwise? My intuition is to disturb them as little as possible, but I also want to help them along however I can, because I know they are in a precarious position. Also, I have a MegaBee patty that I gave to one of my newly installed packages, but the landscape is awash with dandelions right now and the apple trees are in full bloom, so the "package" hive is completely ignoring the pollen substitute. Should I give it to the nuc, or just let them get pollen from the dandelions if they need any? I am assuming that since they don't have brood to raise right now, they won't need a lot of new pollen. Thanks in advance for your help.
