I dont see how they couldnt be healthy theyre basically newborns. Craigslist has good deals to be had for sure, but its often hard to find specifics. Im hoping this person is close. I almost bought a hog about a year ago but I couldnt find any for under $80.
I think the owner is the breeder, but check the owner? How so lol. I know craigslist isnt the best per-say, but at least you can see the animal in person before you purchase it.
