My bees have ventured outside yesterday, we had a lovely sunny day, was not amazingly warm about +8 Degrees too warm for this time of the year. There was hardly any wind outside so they had a good time. They did not come out in numbers a bee here and there but I would think they enjoyed it being able to come out and stretch their wings and do their bits and bobs. There has been the odd dead bee by the entrance as they cleaning them out etc, and I have been keeping an eye on them. All seems fine for now.
Mike found an amazing article, he sent me the link it is of course about bees. Brilliant stuff. http://www.leenks.com/link521574.html
