I personally hate mixing sugar and filling feeder jars. I like to use fondant for feeding. In the spring, having a two inch spacer for your hives (comes in handy for many things) can be used with placing fondant on the frames. This picture is of a 5 frame nuc, with a two inch spacer, and two nice slabs of fondant for feeding. Fondant can be found at most bakery supply companies. You want fondant with only three ingrdients...sugar, HFCS, and water. (No fillers or additives) Most on the market is made by "Dawn foods". Comes in 50 pound blocks, and unused portions can be stored. Hope this helps.
