I was thinking about adding some different bees just to see how they are. Thought about adding some Carniolan, or some Buckfast. I have Italians currently. Then I thought if I added something different, I would need at least two hives of the new bees so I could move resources if need be Then I thought well wouldn’t they all just intermingle anyway? So can you keep different kinds in the same yard and have some kind of “purity “? I get that my bees may already be mutts, but I bought them as Italians so that is what I call them.
