I peeped under the inner cover to see if they had eaten any of the grease patty and it did not seem they had. There were a few bees showing some interest. I think it's just been too cold for them to break the cluster, but they seem to be surviving in spite of the elements. I'll continue to check the grease patty.
My new camera finally arrived yesterday. This has been a very gentle hive to work with. Because I'm so comfortable working in very close proximity to them, I hope to be able to create a very good picture journal. Sometimes pictures do speak louder than words.
When I got Walter Bee I told a friend that I knew I would always be a gardener, but not sure how I would do as a beekeeper. Believe me, I'm hooked! I can't wait for spring to get my second hive.
