I keep ducks and bees no problem. They ignore each other. You might end up with a duck that especially likes to eat bees, and might stand in front of the hive and snack, but it's unlikely to be a big deal--ducks rarely forage in the same spot more than a few minutes per day anyway.
As for moving them inside, you've already received lots of great info. Just wanted to clarify something: bees can be moved readily from one location to another, as long as it is LESS than three feet OR MORE than two miles. Don't try moving them a distance in between that.
Sounds weird, but here's why: Bees will regularly forage up to two miles away from their home. They learn the landmarks and can easily return home at any time. If you move them up to three feet from their normal location, assuming you *don't* put another hive there or nearby, they will see their hive when they return and go to it. However, if you move their hive to a nearby location more than a few feet away, they will fly off and then follow their familiar landmarks back to their old homesite. Very confusing for them, and potentially deadly. If, on the other hand, you're hauling them cross-country and then letting them out again, they won't recognize ANYTHING. Their response is to orient themselves to the new landmarks before flying off. Assuming they don't encounter any familiar landmarks in the area, they'll remember to return to their new site. But if they fly off and come across familiar landmarks, they'll follow them "home" to their old site.
Bees are well equipped for winter as long as they have sufficient stores. They must be either left with enough honey for the winter (a full super for a small hive, two supers for a large colony), or well fed with sugar water WELL before winter. They have a process they go through to make the sugar water suitable for storage, and they won't be able to access the sugar water in the feeders once the weather gets cold, so you have to do this in summer and early fall. Once it gets cold, they will cluster inside the hive and keep each other warm, and will NOT leave the brood in the combs, not even if they are starving to death and there is sugar water six inches away.
Anyway--bees are really easy to keep, but you do have to follow some basic protocol. However, once they're established you can ignore them for a year or more if you have to (if you're not harvesting the honey, they don't need much attention), so if you get busy or whatever, it's not like ducks where they have to be tended. They're a wonderful investment, and I highly recommend them. Just make sure you grab a book or take a class (some beekeeper associations have classes for VERY low cost--our local association has a nine-week class for $25).
Good luck!
