>dead bees when hive  packages in our spring with cold nights,

The sort of drenching used on packages is far more saturating than that
used when drenching established colonies on combs with 1/2 cup (250ml) of
syrup.

Caged bees in incubators have a very different dynamic than bees on combs
in colonies, which clean syrup off one another in seconds or minutes.
 There are simply not enough bees, especially hungry bees, in an incubator
cage to perform the sort of syrup grooming typically done in established
colonies.
