Just set up the two packages and leave alone. I had one hive that went queenless probably in feb timeframe. Interestingly, this was my only carni hive and the queen was from Noble Apiaries--close to where your bees are coming from. Have heard somewhere that some CA queens are having a harder time surviving winters possibly due to potential exposure to almond ag treatments (can't remember where I heard this so take w/ a BIG grain of salt). Anyway, my CA carni was a first year queen that went into winter strong, no mites, and plenty of bees/stores. All my Italians from GA survived their second/third winter just fine (minus one that was "varroa resistant", which succumbed to varroa in Dec--was a first year hive as well).
Anyway, my carni hive went queenless in Feb and, w/ no brood production at the time, eventually became a laying worker hive. Finally got a queen from Ridge Top Apiaries introduced two weeks ago and they are still doing fine. Brood nest is on 2 deep frames and they will start emerging next week-end. I did add two deep frames of brood over two weeks during the first half of Apr to suppress the laying workers.
My point is that bees have a drive to survive so, if they rear a good queen, they will do okay. Just leave them to grow and don't plan to get anything from them and they may surprise you. I would look at re-queening your packages though. Ridge-top's queens are from Glenn Apiaries and VP queen stock (VP queens are bred just up the road from me but a breeder queen is $200).
Chances are, though, the bees may re-queen anyway. If not, I'd re-queen at least one in a few months when they are established for insurance. Plus CA bred bees may struggle a little more in the IA winters. My CA carni sure couldn't take it here (and it's a tad warmer here).
