The bubbles in the eyes are just another sign of an upper respiratory problem. If it goes through the flock slowly, it is probably infectious coryza or maybe Mycoplasma. If it goes through the flock fast, then it is probably a virus. Coryza doesn't necessarily smell bad - which is what you read in books in the description of "classic coryza." It depends on what stage of the disease you catch them. All this info I got from the extension poultry vet when my flock was sick.
You can treat with antibiotics - Sulmet or Tylan for coryza; I'm going to have to look up what the avian vet I talked to recommended to cover both coryza and mycoplasma.
The poultry vet I talked to about my flock did not recommend anything dramatic - such as destroy the flock. If you have free-ranging birds, or even if they get to go outside where they are exposed to wild birds, your flock will be exposed to stuff anyway, even without bringing in adult chickens. I myself, can't see killing off my flock every time one of them comes down with a respiratory disease. I don't sell my chickens, though. If you do, then it's probably best to get them tested.
I treated mine, it took a while, but they all got better, and have remained well.
