Thanks Apis,
My bees definitely exhibit their Russian genetics. After your advice on the SHB I found, I did a complete inspection and found no SHB damage or even eggs/larvae. I also observed one of the workers dragging a bee larva out of the hive and tossing it off the landing board. I picked it up and looked it over and it had a very small almost translucent mite on it. We are in a dearth right now and I assume they are using this time for some housecleaning.
