I think mine stored it - I bought a packet from Paynes, and my WBC took it all between Jan - March, although they had several full frame sof stores. I was a bit paranoid about them starving. When I had my first inspection in the warm spell early March, they were flying well, a good deal of brood in all stages, but pretty packed with stores on a brood & half. I took a frame of stores out and replaced with partially drawn comb, hoping they would expand more quickly. I put a super on last week with some undrawn foundation and about 5 frames drawn (it's all I have), will do a full inspection tomorrow, but peeked in the super this pm and although lots of bees in the super not much more drawing of comb happened yet.
