I just talked to a home owner who inherited a hive from the previous owner of his house, and he would like it removed.
I haven't been to look at it yet, but he says it is mounted on a fence post and has hinges to open it.
I seem to recall seeing some hives in Europe that had doors on them, and know very little about this style. I'm hoping I can move them to a Lang hive without too much hassle.
