In my area, a local nuc easily sells for $200 - $250. At this point, money is not my main objective, so I underpriced the bees by a considerable amount. Mostly, I just want to test the waters and get a feel for the process.
I could probably easily sell 8-10 nucs as long as all 6 colonies pull through to spring, but I'd like to keep a couple splits for me and make some honey. Also, I wanted to limit the number of splits for sale because it's still a long way until the pollen comes rolling in, and I wouldn't like to disappoint anyone or weaken my own hives too much -- because that would mean less honey!
Still it's kind of fun to sell some bees. Hives don't seem to grown on trees, so it's nice to actually make this hobby pay for itself.
