Aroc, greetings: keep young queens, give lots of room. A crowded hive in spring is just asking for a swarm. Requeen this spring, this helps but is not guaranteed to prevent swarming. The main thing is to prevent overcrowding.
Some clip wings of the queen, I do not as my hives are all on stands and a queen with clipped wings just falls to the ground when she attempts to fly. Once the clipped queen is grounded from an attempted swarm flight there is little chance she can crawl back into the hive which may have hive supports five feet away from the entrance and one stand may support 5 hives.
A queen with clipped wings on a hive that is on the ground may be just fine, I don?t know as I said, my hives are all on stands above the snow line.
I hope your bees winter OK, Montana winters can be brutal.
Blessings
