It was a very nice sized swarm in a tree, that wasn't to difficult to get. I'll estimate between 10-12k. I laid a sheet down on the ground below the branch, placed a box on it with some drawn comb, and shook them down. Took about two hours to get them completely out of the tree, but I'm pretty sure I got the queen. These bees went into my top bar this morning, so I'll check on them in a week to see how they are getting along. For good measure, I added a frame of eggs/larva to the box.
