You'll find that beekeepers (until they learn, which takes years) tend to drop their hive tools into the grass with surprising regularity and can never find them again after that. You'll be well-supplied with them assuming that you let bees and their attached beekeeper onto the farm, like golf balls next to a golf course. With a bit of grinding (the hive tools, not the golf balls or indeed the beekeeper) they could pass as back-up knives.

Of course Doris being Doris will invent some new recycled hive tool from a rusty old tractor bolt or something, so perhaps her cast-offs will be less useful.

So that is one benefit of letting bees in. Another is their ability to herd sheep. I find that in the first few weeks sheep are attracted to the hives which they tend to push around quite a lot with the itchy bit of their backs. Give it an extra few weeks though and you'll find big semi-circles of ungrazed pasture around the fronts of the hives. Potentially useful for managing grazing, no?

hope that helped
