A bee colonies natural way of propagation, by splitting in two. About half the bees leave the hive, with the queen, to try to set up home elsewhere. A new queen hatches in the remaining colony shortly after.

About The Author
I am a beekeeper and an allotment grower and this site features articles on those subjects including recipes made from the produce from my allotment and from my bee hives. I have an interest in a great many things (too many actually) and some of those experiences, and the joy and learning I acquire from them, may also randomly appear here.
