Large number of bees crawling out of hive and freezing to death
Hi, today I noticed a large number of dead bees in front of one of my hives. I thought it was unusual, but I left and didn't think much about it until tonight, when I saw that the number grew to very abnormal levels, hundreds of them, all in one big mass. The bees were crawling around the top entrance and falling to the ground and freezing to death. I suspect dysentery to be the cause, as I saw some feces around the entrance. So, my question is should I block the entrance with screen or let them be? I'm not sure if it would change the outcome of the hive, but I want to save them if I can.
