Milt,
As you mention that you have thrown two colonies together to form one
after bear disturbance - and are now seeing bees hanging outside, maybe
it is that the two remnant colonies have not mixed.
One occupying the combs as expected, the other squatting on the doorstep.
Increase in numbers during the evening and night time as foragers are
back at base.

Any better explanation!
Peter

P.S. Lousy weather here in South central Manitoba, with a very
restricted harvest likely.
