Insulation

So I've removed exterior hive insulation twice and replaced it twice since we've had some cold evenings of late. I decided to wait until June 1st to pull the insulation for the rest of the season. I've also been changing my entrance reducers morning and night. At night I change the entrance to the half-inch notch and in the morning (after it gets about 40* or warmer) I pull the entrance reducers all the way out. Congratulations to Sterling Muth who successfully re-queened his hive!
