Southern Ontario, Canada. Second year keeper I have two deeps of brood, and two deeps of honey, and the whole thing is full of bees. I missed the boat for splitting the hive earlier as I didn't realize this was something you should do. I thought it was more an 'if you want to' kind of thing. So I was wondering if a colony can be too big for overwintering. I'm also not sure how much honey to leave them. Last year a local veteran said around here the bees need about 1 frame per month of winter (meaning 5-6 months here) but that was for a colony with 1 brood chamber. Should I just double it? The little buggers are soon going to need another super, but until I figure out how much honey they need I'm afraid to harvest any. I'm also fairly certain my hive shouldn't be five deeps tall.
