How's our Bees doing this long Winter ?

It's been a long tough Winter for our bees but we are looking at some warmer temps the next few days.
Despite how cold some days have been this Winter, the temperature in each hive remains around 34 Celsius, the bees maintain this temperature by constantly moving around and eating lots of high energy honey.
Each of our hives will actually eat their way through roughly 30 to 40 jars of honey just to get through the Winter, in fact, to help ensure there's enough honey to last the Winter they kick all the drones (male bees) out the hive to die, the girls are too mean to share during the Winter !
