>Another question-- of all i read (unless i missed it) there is no clear indication of when is the best time to do this-
Because it's an art, not a science. You need enough bees (which will change by time of year) and enough stores (which is easiest during a flow) and enough time for the split to build up enough to get through the winter. Actually, if you read the FAQs at the bottom you will see things like "how early..." etc.
>Another simple question-- why couldnt hobby beek have a 3deep colony--ie huge colony-- will the bees swarm if they have plenty of space?
Yes, the hive wants to reproduce and will given the opportunity...
