This year I made enough extra overwintered nucs that I had a decent amount to sell. Without advertising I have them all sold. One of the potential buyers was interested in all I had but when they found out I had deeps was no longer interested.
I have always used deep brood boxes, so deeps are easy for me to make. How do the more commercial-oriented decide whether to make deeps or mediums? Since I am making them as overwintered nucs I need to have a plan before the season starts.
I had a tuff time finding medium nuc's when I needed them , i had switched over to all mediums and I finally found a guy that would make them up with plenty of notice . With everyone going to all mediums for varies reasons I would think it would be a good market
I'm going to guess that 90% of commercially minded beekeepers keep primarily Deep brood chambers. Er go why most nucs on the market are of the Deep variety. I think for a sideliner producer it would be smart to divest into the medium market to meet the niche of people wanting medium nucs. Especially when i see the prices people are getting for medium nucs.
For someone like me that has already invested into 15,000 deep boxes, and 30,000 shallow honey supers, I am not going to add another box size into the fold for such niche as medium nucs.
I am in the opposite direction -- running all medium frames -- I decided to discontinue my few deeps several years ago for interchangeability and efficiency. So I only offer medium nucs If someone wants deep nuc, I refer that person to a friend. As long as you can sell out with one size, there is no need to expand the options. If however you want to make a big expansion, medium nucs would, as mentioned above, be good if you have hobbyists in your area (possibly due to advocates in clubs or courses) who prefer mediums. You could offer a package deal of a deep nuc, a deep box (eight or ten frame, depending), and the extra frames of foundation to fill the box.
I hate making med nucs. It seam just about the time i am ready to ship them they swarm.. I have one or two people ask. If I get brood in meds I will make them up. But will set a deep on top of them. Just to cover my but.
I'm still trying to think how I would make medium nucs. My nucs up until this year have been for personal consumption. I can easily overwinter a simple 5 frame deep. I don't think a 5 frame medium would have enough bees to stay warm. If I would make it too early they would swarm too.
