Fantastic! Not that they have mites, that's not fun, but that it wasn't more serious. I just caught up with this thread this morning and really glad the problem was found. Again no idea what you can get there, but I have used the Sevin dust on the birds and I also found a Sevin spray that I used on the roosts, not the birds. I even spray in the nesting boxes with the stuff before adding the shavings. No ill affects in the birds and it seems to work.
