My two cents....
If you're set on beekeeping (which is very addictive
), then here's some steps I suggest. The cheapest route to take is what was advised above - find another beekeeper to give the initial check on the hive. Like it was said, they may be rather wild, and there may be some illness in there that you wouldn't know the signs of at first glance.
If you can't find someone, or choose to do this on your own - for whatever reason, stong willed? the thrill of it? because it seems exciting?
...... then you'll probably want to invest first in the bee suit, a smoker, and one or two hive tools (it's a small crowbar looking thing). Plus, read up as much info as your brain will hold before getting in the hive. That way you'll sorta know what you'll see, and what to look for (brood, illness, etc.). Expect it to be a tangled mess of burr comb, but that's fixable. And take a camera and/or note pad out to the hive with you for notes to look over after you're back in your house.
Don't be discouraged though. They're probably pretty strong, or they wouldn't have made it in the first place. If the hive parts and bees are good (not dieing or falling to pieces) you've got yourself a big savings. Beekeeping isn't exactly an inexpensive hobby, but the rewards from it are worth it. But it's the initial start-up that's costly - bee suit, smoker, hive tool, maybe a feeder right away - can be bought for under $200. Two hives with bees would cost you another $50 per super, with frames, and the bees are $50-$100 for just a small start. So I'm guessing you might be saving at least $400 with those two adopted hives.
Good luck, and happy beekeeping to you.....
