Last year I overfed my bees in summer and had to remove frames of stores as there was so little room left for the queen to lay. I use 10 frame dadant and currently have 3 thriving full hives, one nuc from a split and two caught swarms. There is very little forage around at present and the bees have few stores. As a rough guide how much syrup should I give? They seemed to just keep on taking it down until the brood boxes were choked with it last year.
