FWIW, I opted to have 10-frame medium for this new nuc with 2-frame feeder in it. The queen is still not laying and should in about a week. This one box hive would be the weakest of my four. I am going to leave it alone and see how they build up until cold sets in. If they build enough stores and bees then I might over-winter it as is. If they seem too weak then I will have to combine them with another 10-frame medium hive that has 2 boxes so far.
