I got my first chance this spring to do a complete hive inspection today. Everything looks good (they're putting up plenty of honey, enough that I added another super), but the one thing that struck me as odd is that the bottom three boxes (one large, two mediums) are all full of brood. It's a nice pattern except on a couple of the outer frames which are spotty, but still that just strikes me as an awful lot of brood. I'm pretty inexperienced (this is only my second year) but is that normal? Shouldn't they be reserving more space for food?
