Re: One colony is failing already
>>The brood looked all dead in both supers.
Dead larvae was evident through partially capped cells.
Some bees looked like they died before they could chew their way completely out of the capped cells.'
probably mites, but there are other brood diseases.
i would 'consider':
1. making sure this hive doesn't get robbed out by any other bees.
2. having your state inspector take a look.
3. sending a sample to beltsville.
especially if the dead dark brood passes the 'toothpick test' for ropiness, which would suggest american foul brood.
getting a certain diagnosis will help you decide what you can do, or not do, with the comb and stores.
beekeeping since june 2010, +/- 20 hives, tf
