See!! Now your on the right path.
This is also a prime example of why you should always quarantine any new birds you plan to bring into your flock. This gives you time to notice if they show any symptoms of disease before there is cross-contamination, and to respond to it. Even when you do this and there are no symptoms, the new birds can still be contaminated and already passed the symptom stages. It's always a gamble, but you can take steps to minimize the risks. Take Coryza for example. Once contracted, birds that survive the symptoms are carriers for life, easily capable of infecting any other birds they come in contact with. You might have a single strand of this highly contagious virus from this bird on your body, and walking into a hatchery would put the entire facility at risk.
After thinking what u said, maybe vet school wouldnt be a bad idea for what u want to do. Then you would have the knowledge to do Anything you wanted to do concerning animals. Shelter, care etc.
