I see 2-3 crawling bees on the ground a day some appear to have a slight K wing others don't, some try to fly others not so much , I've even seen a few stop to suck nectar on some clover. The one thing that EVERYONE of them is doing is beelining all in the same direction it almost like they are on a string. I saw one of them get booted from the hive but it wasn't a big fight to the ground like what happens with robbers. I see nothing out of the ordinary inside the hive and no noticeable feecess inside or out so I think that would rule out nosema right ? Could it be something as simple as robbers getting their butts kicked ?
