Not so good

I looked at my bees today and it didn't look so good. I am going to do an in depth inspection. It definitely looks like I had my first swarm. Not what I wanted and I still can't figure out why. All the books that I have read, talked about over crowding as the main reason that bees warm. My bees had plenty of room. I did read one book and this may be the reason- It stated that bees have a natural tendency to swarm in spring and that is how they "populate". It also stated that a beekeeper should check their hives every 10 days and destroy any queen cells. So now I wonder if the other hive is going to swarm and I also wonder if the hive that did swarm how long will it take them to produce a queen. I may have to take a frame of brood from the strong hive and place it with the weak hive. Well at least I am getting some "practice" on being a beekeeper vs being a bee owner. I will try to post some pictures of this new adventure.
