Hi @Jstrano, as a new beek you should just follow the advice of your mentor, or at least a reputable bee book. You need to have a clear idea of what will happen when you install your nuc/s and what the colony’s needs are. My advice is to not try something you have read on the internet… ie. don’t run before you can walk.
Your new bees will need to be able to cluster and if you put empty frames, or large spaces, between their brood frames you will potentially be splitting the hive/colony and, again potentially, they will end up ignoring half of the brood. This brood might chill/die - of course this can depend on your location and the climate.
Look after your bees traditionally to start with, then branch out when you have experience.
Also, don’t combine your weak hive with a new nuc quite yet - give the new girls a chance to get established for a week or two. Do you have a queen in your weak hive? If you do, and you are planning on combining them with another hive, you will have to kill that queen. But don’t do that until you are certain the new colony is functioning well. Then kill her and give it a day (at least half a day) for the weak colony to realise they are queenless before uniting them with the other hive - you want to avoid a huge fight!
Hope that helps, Paul
