MG is almost everywhere. I can't imagine any hatchery never having a run in with it. Several people I know have purchased chickens from Ideal that were MG free.
Now, in reality, the only way you are going to get MG from day old chicks is if it passed through the egg or the handlers are contaminated. This decreases the chance of MG by around 90%. Chicks born with MG will most likely not shed the disease until they develop symptoms, many days later.
Finally, chicks need to be brooded when you get them. If they have MG you will know it in under a month, probably much faster. Even chicks should be put into quarantine.
So, let's keep this whole thing in perspective. With proper biosecurity, even if Ideal does have some infected breeds, you can keep things under control.
