mine were out flying yesterday, it was a welcome sight. I think they liked it too, bee poop everywhere.
I had cleaned out the bottom board the day before, and with all the racket I was making scraping out dead bees, they didn't even come to see what I was doing, and it was plenty warm enough. It made me nervous enough to lift the top to see if I could find the cluster. there they were looking right at me.
Glad to see them out and about yesterday. They still have nearly a full deep of stores.
