I picked up 2 nucs on the 26th of April and installed them the same day, both had capped brood. I didn't see the queen on the first one but saw one in the second one nuc. I put top feeders on both and have seen lots of activity the last week. I opened up the first hive today (the one I didn't see a queen in) and there is a queen cell on one of the frames, the second hive is fine, saw the queen again today. I contacted the seller and he said all nucs were inspected and had a laying queen when picked up but sometimes they supercede. He offered me a queen but I can't pick it up until Saturday. Should I go get the queen or wait and see if the cell hatches? I know I will be a few weeks ahead if I go get the queen but it's and hour and half drive round each way to get it but I will do it if it's best.
