How often is a swarm to large for a deep hive body? The last swarm I caught I shook into two deep hive bodies. I gave it to a friend and we knocked it down to one deep for him to transport home. It more or less stuffed the deep box full. I have two swarm traps near the yard where the swarm came from and I dont think the swarm would have moved into either one being one is a medium box and the other is a deep. I dont see a swarm moving into a cavity that it already fills. So Im just wondering how often I may run into this situation or how often I could miss catching a swarm because it chose a larger cavity for this reason? 1 in 20?
