Georgia is getting very full of bees- I think it would be a good idea to split her soon. The problem is that I have only seen two drones around the hive so far this spring. Without a sufficient supply of drones any new queen that is made after the split will not be able to mate well, and that will not make for a healthy hive. I do hope drone production starts up soon.
Here is a picture of the pussy willow. It was very full of bees- you could here the hum from quite a distance.
