I recommend you install your bees as planned and wait one week after installation before inspecting them. This advice applies even if your queen was alive upon arrival, but discovered dead in front of the hive a few days later. After a week, your bees should have built some comb and if there is a queen you will be able to spot her more easily on the comb. Comb also allows you to look for eggs which is evidence that you have a queen, even if you are not able to find one. (Remember, if your queenspotting skills are not developed.
If after a week, you are still unable to find a queen and there are no eggs, ask your supplier to send you a replacement queen. However, be sure to double check for eggs in the comb when she arrives and before you install her. Some shook queens take a little longer to start laying.
