I just inherited two hives. They're currently located across my yard from one another at the advice of the previous owner who thought at one point a hive was being raided by the other hive.
One hive is very active while the other is not. In fact, the 2nd hive is VERY quite. I was surprised to open it up and find that it is full of bees. However, I couldn't locate any brood (too early in the season?) which makes me think I need to get these guys a new queen. Yesterday & today the slow hive has appeared to be VERY active but I'm starting to suspect that the bees from the hive are coming in to grab some free honey. I can't be sure of this because I can't tell the bees from each hive apart but I do know that I don't see a lot of bees coming back loaded with pollen at this hive. I just see a whole lot of chaos out front.
My question is, how close can I put these hives to one another without worrying about one hive overtaking the other?
