Hello and welcome to BYC!
I am sorry you are having so much troubles. Unfortunately many birds from auctions are sick. Very few people take birds to auction that are healthy, they take the sick ones. You are better off knowing your breeder, getting birds from friends or hatcheries. Even off the bulletin board from a feed store...but auctions, flea markets, swaps and craigslist are no no's for the most part.
Bubbles in the eyes mean either MG or Coryza. Both are bacterial respiratory infections. Coryza will cause gummy eyes and the face will smell really bad. MG usually causes more runny secretions, not so sticky. I would get all your birds on some Sulfadimethoxine or Duramycin. Both of these will take care of respiratory issues. If you have really hard water, you will need to use RO water or Distilled water. If the meds turn blue in the water after a couple of hours, use Ro or Distilled...you have hard water. Make a new batch daily. You can order these things on line from many pet and poultry supplies. SOME feed stores will carry them. Both of these bacterial infections stay with the bird the rest of their days. So any birds you add will be subjected to this disease.
Good luck and I hope you can get them cleaned up soon!
