Re: swarm control-brood nest
Your other 2 hives may have already swarmed. If you still see swarm cells stop cutting them out and do splits as apis maximus suggested, with queen cells in each hive. The queens may already be gone and you could end up with queenless colonies if you continue removing queen cells. The fact that they are teaming with bees does not mean they did not swarm. I've had booming colonies throw very large swarms and you would never know it based on the amount of bees left behind.

To everything there is a season....
