I picked up 5 packages on Sunday and installed them today and everything went great. However, in one of the packages the queen was dead. I thought about transfereing a frame or two of brood from another hive but didn't do so as it was getting late and dark. I opened and inspected the hive I was going to steal a frame or two of brood from and looked at three frames and on the third frame there was a capped queen cell. I am thinking about moving that frame and maybe one or two more over. My fear is that the queen from the queen cell once hatched will not be able to mate successfully as I have not seen any drones at all yet. Am I wrong in thinking that it is too early and cold for a queen to successfully mate in Iowa during the first of April? I have called the person who I got the packages from but haven't heard back yet, but he did say that he has extra queeens in case there is was a DOA queen. Just looking for some of your thoughts. Thanks in advance for all the advice.
