Re: Handful of bees in the grass that can't fly. DWV, Tracheal mites, another virus?
The K-wing sure looks like symptoms of Tracheal Mites to me. After seeing the video of your queen I'm thinking that the "indentation" in her body is probably some type of genetic birth defect, and it appears to have been passed along to some of the worker bees.
For both of those reasons I would plan on replacing your queen with one from a reputable queen breeder in the spring, and that should eliminate both of these issues.
To everything there is a season....
