I lost my first hive i found out. I now have 3 hives left. also my strongest hive has about 1/2 of the bees dead i believe. the other 1/2 seems okay (hope they have a queen) i am sure that the dead bees are starved out as they have thier heads stuck in the combs. I have mountain camp on all 4 hives. it has worked great until recently. they have been taking sugar all winter. i think they starved because they ate the sugar directly off the frames and left a hollow dome of sugar which i don't think they wanted to come up to eat. It may have been to cold to come up out of the frames to it. I added more sugar to the hives so they now have it on the frames again. should i wrap them to add more warmth so they can possibly move more often?(moisture has not been a problem) It has been a very long cold winter here in Montana.
