Im talking about the person who willingly sells sick animals and says it's no big deal. When you potentially kill peoples pets because of your greed / ignorance or whatever then it IS a big deal and if someone ever did something like that killed off my Too, well, Id probably end up in jail over it.
Even if it really was no big deal, still, that kind of $#^t needs to be told to the potential new owners UP FRONT, so they know what they are getting into, and can potentially inoculate their existing birds, quarantine the new ones longer or whatever it takes to prevent passing a sickness on.
