One can only conjecture from this distance, and without any testing. I see
one occasionally that would fit your description. I put it down as "weak
stock."
One possibility that occurs to me, is that, in this time of dwindling
bees, there are fewer and fewer drones out there, and the probability
increases, of the young queen mating with her brothers. This brood becomes
very poor, as a lot of it is not viable. This coupled with bees that have
poor hygiene, could lead to symtoms such as you describe. Tracheal or varroa
damage, with associated viruses, and poor-hygiene bees could also be an
explanation.

My primary means of dealing with such bees is requeening, with a cell from
my own vigorous stock, or a purchased mated queen. It usually cleans right
up, if it is not too late in the season. I doubt if terra would make any
difference, unless you have european foulbrood, which is another thought that
crossed my mind. With EFB, the larva dies in a curved position, not quite so
flat and centered on the bottom of the cell, and of course, doesn't string. I
have seen EFB, chalkbrood and sacbrood, all in the same hive, in different
cells (what else could better tell you that it is weak stock!). EFB is not
common, but pops up now and then. Antibiotic would "cure" it, but you still
have susceptible bees, so I'd requeen also.
