our only beehive has been discovered dead. no live bees at all. the bees were on the floor of the hive, and when we checked the frames, we found no brood, but we did find 2 popped queen cells. they had a lot of honey a whole super and a lot of their brooder frames. we kept finding this weird red jell in some of the frames. also, the whole thing is crawling with ants, but the bees are dead without a struggle. why did our hive die???
