Our last inspection day showed us how easy it is to loose your bees to starvation. On the inspection the week before there were eggs, larva and stores, everything was fine. After a week they had nothing. There were no stores, no larva and there was lots of uncapped brood. One hive was so bad it had 4-5 thousand dead in the hive.
I made up gallons of 1:1 sugar water and fed all my hives with rapid feeders on the crown boards. I topped them up though out the week and now there all looking great. The combs are full of syrup and the queens are laying eggs like crazy.
