So I went to my hive today to make sure the queen got out safely (turns out the attendants had died so she was blocked in), and I noticed some really gruesome behavior on the back of the hive. I pulled the outer cover off, and I saw at least 100 dead or dying bees on the inner cover, next to the inverted mason jar I use for feeding. I brushed all of the bees off, replaced the jar with a new, full one, and put the outer cover back on.
Well, my inner cover has a notch which acts as a second entrance, and this notch is facing the back of the hive (maybe I have it on backwards). Never the less, this notch is the scene of something I was really hoping not to see. Bees are fighting, trying to get into the hole with the mason jar, and it just looks like a warzone. I'm using an entrance reducer at the front of the hive, and not much activity was going on there.
So, I decided to smoke the bees near the inner cover and plug the hole with two sticks. I waited around for about a half hour, and despite the bees not being able to get into this entrance, there is still a lot of fighting going on at this part of the hive. I also noticed increased activity (including fighting) at the front entrance after I plugged this hole, but I guess that's to be expected.
I was hoping someone could give me some advice on how to help my bees survive this robbery. Also, I feel like the worst beekeeper in the world, but if someone could tell me whether or not this is 1) normal and 2) whether or not my bees have a decent shot of surviving this ordeal, that would be awesome. In fact, any advice would be great.
