so based on the speed at which my bees were working , they had a frame and a half to fill, and i decided to nadir a second box. in hindsight, bad move, the weather is starting to cool and the have slowed production considerably to the point where they have not yet finished the first box. i am thinking bout taking the second box out and leaving them to the one box for the winter which surely they will fill soon. with the second box out i figure they will have a smaller space to temperature regulate and therefore winter better. is removing the box ok, and will one box be enough to winter successfully or should i look at sugar syrup or something? the winters here in adelaide south australia are cold but not unbearable... 10 degrees celsius... any thoughts?
