Hive population is a delicate balance... All the bees have a job and need to be able to do that job. A nuc has all the nurse bees it needs to cover the amount of brood present. A package is specifically shaken to be mostly nurse bees because at a specific age they can draw comb and other bees cannot. You dump all those extra bees in with a nuc and they will likely think they are over populated and make swarm prep.
I never tried it so these are just my assumptions.
ImaNewBeeToThis..... If you are going to buy a nuc and a package, you could likely find an overwinted established hive for that amount.
As someone new, I would go with two hives, likely one nuc and one package, learn all you can from the two, grow into beekeeping with your two, very different hives.
There are two advantages of a nuc that I see as important for newbees. 1. It gives you essentially an active hive so there is less of a change of making a boo boo on day one. 2. It is more likely to be local than a package which I value highly.
We have a guy locally who sells "local nucs" but he buys the queens heading up those nucs from CA. That isn't going to be a local nuc for long.
I'm overwintering six carnie "nucs" in double five frame medium boxes. The queens came from California, they are on small cell foundation, and they're chemical / treatment free, I'm not sure that they would be considered "local". ...
Well I have walter Kelly next door to me so I'm going with their nucs.
