2 or 3 Brood chambers? 2 supers?
I'm still very new to beekeeping and I noticed that some apiaries have two or three brood chambers and one or two supers. Is there a reason why there are not more supers? I mean, it's certainly possible that I've missed some that have more than two but I haven't seen any so far.
And is the reasoning for three brood chambers that it will create more bees and thus, give you a higher output with more frequent honey extractions?
Any advice you could provide would be greatly appreciated.
