New bee here in the Portland Oregon area, still raining here which is odd but other than that it sounds close to the clime of yours (last frost date of April 15th). I see a lot of talk of mediums but in Walt’s writings I see 1 deep and two shallows. I have been getting equipment used from all over since people found out I was bee keeping and have a 10’ stack not in the “yard” at this time. All of it different (MB must be laughing). I am finally getting to my questions: Appears that it is a deep and two shallows that are manipulated for the CB then a huge stack of supers. Is it not possible to extract the supers so that the bees do not have to crawl 6’? Why the tall stacks? Does it matter what size I use for supers? I don’t think that the super size is really any issue or did I miss that? Even at 6’3” I don’t see the point of working above my head. I have had 100% of my hives swarm this year and have suspected it is because of all new plastic F.
