I want to thank everyone who replied to my last question...
I'm about an hour south of Ottawa, Ontario - hunting around for bees to start 2017.
Pretty much all I can find around here is four frame nucs, pretty sure they are all deeps.
I have read several books and many of them suggest to use medium boxes for brood (3 mediums instead of 2 deeps) for the ease of handling as they fill up. This might be a stupid question but I'm wondering if bees prefer deeps over mediums or vice versa.
I understand that full deeps could be a bear to handle but I'm more interested in what is best for the bees (I'll worry about my back later).
Thanks to everyone for their opinions!
