I'm in Mexico and was promised a pig for Christmas - these were the conditions I traveled to Mexico with my BF under ;-)
We found a guy who had pigs, and his 3-week-old ones were ADORABLE! He explained these were too young to be separated from the mother and had a higher possibility of dying but said we could choose from the 8-week-old ones for 450 pesos. Compared to the babies, these 8-week-old pigs looked HUGE! We told him we'd come back after asking around some more.
Of course I went home & did A LOT of research on how to take care of a 3-week-old piglet.
