As some of the members here know, we have had an extremely mild winter in Texas along with half the other states out there. I experienced something today however that kinda worries me because of all the warm weather and I am hoping someone with more experience can maybe explain to me what I am seeing. The past few days had turned off very cold and we finally got a little snow that lasted for half a day as the rain washed it all away. It warmed up today however and then late this afternoon I noticed that one of my hives had a very large amount of bees outside, say approximating a few hundred. My other hives were not exibiting this behavior so I had to find out what was going on. The temperature I am guessing was about in the mid 50's so it just seemed a little cool for the time of day for them to be out in a large number like this. After suiting up I went out there and watched them and they all seemed to be excited and buzzing. A few of them were standing very still on the front of the lower box with their tails extended upward which I take to be a defensive mode??? Others seemed to be talking to one another and walking all over each other trying to come and go, but none seemed to be bringing back any pollen. One bee I saw was a drone, rather big with bigger eyes but definitely not a queen. So I popped the lid and looked inside and it seems they may be running out of room and food. I am assuming that the queen has been producing due to the warm weather and as more bees have been hatching they have also consumed more food. Is this also a signal of a possible swarming that I am seeing? Without tearing down into the brood nest I can't tell what is going on. Is there a signal of this before they do it? Because it was so late in the day I felt they would not swarm yet, but fear that tomorrow when it gets even warmer they may decide to swarm while I am at work in the morning. Since they seemed to be getting a little crowded I went ahead and placed a deep super with some frames on top and moved a frame from below up into it. Tomorrow I will need to get some food in there. With warm temps would it be alright to feed them 2:1 syrup in a top feeder? I know this is alot of questions and I appreciate whatever help I can get in understanding this behavior. If things are going well I am hoping to make it through my first winter without losing any of them.
