Live in northern utah. Inspected a hive about a month ago and found no capped brood and several empty emergency cells. I bought a queen that is marked. Put her in and released her 3 days later. Three weeks from being released (today) I checked for capped brood and found non. I saw her walking around looking fat and healthy. Why isn't she laying? There is plenty of comb with no honey in it she can lay in. Maybe I was sold a queen that wasn't mated? She looks big and fat though and I think she looks mated. I plan on just letting it go and see what happens. I expect the hive to get robbed out in a few weeks when their numbers get small. The population is down a lot from last time I checked 3 weeks ago and the old bees are dying off it appears.
