I have a hive that seems to be just not thriving. In tired of opening it up and seeing them not growing. I'm going to shake them out and put a swarm I just captured in it's place. What should I do with the small amounts of brood that is still In the weak hive. Is it a bad idea to add it to another hive? I'm leary of doing this because something is causing the hive to not build up, but I'm not sure what. I haven't seen any signs of foulbrood, but who knows. If I just shake em and dont re use them I have frames of rotting brood laying around. What's the procedure here?
