The last 30 years of experience tells me that your answer from vtmom30 is the best answer you will get.
It does depend on the pig but as you stated you are getting piglets, they will be raised knowing that chickens are not dinner as long as dinner is sufficient in nutrition.
I have horses, donkeys, chickens, quail, geese, pea fowl, guinea, pigeons, sheep, muscovey and regular ducks, a potbelly and a julian oh and I just got 2 Jersey calves because as you can tell I didn't have enough! My pot belly (Maddie) and one of the roosters (Leo) are great friends they lay and sun together and I don't mean they lay close, I mean they are touching!
As far as the virus thing is concerned, virus must be brought in so if you practice the good habit of keeping new animals quarantined upon arrival you should be good and when I am sick I just use that to my advantage after all like I tell the kids "you want ME to feed what if I make the animals sick!"
