So about a week ago I installed my first, what was supposed to be a Nuc but everyone says it was a package. It had a queen in a cage for at least 4 to 5 days before I opened her up. The man who sold me them criticized me greatly saying that I probably killed the queen but most people here on the forum say that she was exposed to the workers long enough to be accepted. I was told not to open the hive for 3 weeks...are there any signs I can look for to know if my queen is alive? I notice a lot of worker bees are coming back with their pollen buckets full, some have said that is a good sign. Anything else?
