It has been 23 days since I added one frame of brood with eggs. Any eggs laid that day should have emerged today.
3Reds and I went out to look at the hive again. The temp was in the upper 70's today. The first thing I noticed was that they were a lot more aggressive than last time. They were aggressive 23 days ago, but they didn't follow me across the yard and into a shed, like they did today.
The outer frames had quite a bit of uncapped nectar/sugar syrup and some capped honey. The two middle frames had capped larvae and some pupae. I still did not see the queen, but when I got past the two frames with brood, the bees took their aggression up a notch. We were wearing jackets, rather than suits, and 3Reds had already taken five bee stings in her legs. I got a couple of ant or spider bites on my right leg. So, we chickened out and put the hive back together. We added 1:1 sugar syrup to all of the hives, since I think we need to keep our populations up due to the yo-yo weather we have, and closed everything up.
I'm pretty sure I started a robbing war. This hive only has one box. I shrunk the entrance to help them out. One of the three already has a robbing screen, and the third hive has a small entrance. Hopefully all will be okay until tonight. I can add a robbing screen while everyone is asleep.
The temp is supposed to drop into the thirties, with the first 20* drop into the 50's expected in about 90 minutes. So, I don't think the bees will have time to rob each other completely out.
Back to the so-called queenless hive: I saw no drones. My guess now is that the hive really does have a queen, and I just missed her.
