The most common diseases that cause bubbly eyes in chickens are Mycoplasma gallisepticum and Infectious Coryza. Birds with these diseases are carriers even if they are not showing symptoms. Treatment only treats the symptoms, it's not a cure.
The birds that are not showing symptoms are the ones that may be resistant and will pass on their resistance to their offspring. But, if you dose them with meds, you won't know if they are resistant or if you are masking the symptoms with meds.

The Cornell website above is a good place to read about avian diseases and the symptoms.
If you don't want to have a bird tested, that's your choice. But you are only guessing at what is wrong and what can be done, if you don't have any testing for a diagnosis by a professional. If you want to keep birds that have had serious respiratory symptoms, that's also your choice.
But if you want to breed and sell birds - as a responsible breeder & seller - you should know, not guess, about the health of your flock. You should not breed or sell offspring from birds that have had serious undiagnosed respiratory symptoms. Even if their symptoms have resolved, because they could be carriers.
Think about how bad you are feeling right now. Would it be fair to sell birds to other people and have them come down sick?
You should also have the means to care for your birds properly. Having a space for quarantine or separating a bird is a basic necessity. I know you are excited about hatching & selling chickens but there's more to it than simply hatching and selling.
