al, i am with apis.........
you could liquefy it and feed back, i wouldn't feed them the crystallized solid, like apis said with crystallization, they will get what they can from it and discard the crystals, or leave the remaining crystals. (similar to crystallization in frames........clean up or use what they can, drag some crystals out, or just flat out leave the crystals in the frames.)
and like apis, i would just feed them sugar, and liquefy the crystallized honey to sell.
