If your colony made it thru the winter and is packed with bees. You have to divide. If you don't divide your hive will more than likely swarm. When the bees swarm, that hive usually produces no honey. All the field bees leave and it takes them weeks to recover.
If you have too many bees and do not want to run any more colonies,
