OK. the last meal...
In my country bees are feeded in time and dry sugar is used in April and in May.
Of course if I have brood in December, the hive is already dead. The hive consumes so much food that we cannot do nothing.
I have noticed such hives and feeded in the middle of winter , but however they will be in bad condition, which means practically dead.
I do not inspect my hives in winter, and still they all are alive in Spring.
