The hive with no bees at the entrance is doing fine. For what ever reason this particular hive will stay clustered when all other hives flying say 50F. But if sunshine and above 55F this particular hive appears well, with over a dozen guards closing watching entrance with is reduced to 3/4 inch.
To cold as of 3/8/18, so I cannot inspect any hives, but all hives flying,
on warm days.
