Answer 1

Corn will make then nice and fat. Fat is good, in ducks.

Answer 2

It's not so much WHAT they feed the ducks/geese, it's HOW MUCH they feed them.

Birds raised to become foie gras (fatted liver) are kept in tight cages so they cannot move (exercise) and are force-fed. This causes them to gain weight and develop a fatty liver, which is then prized for its richness amond some gourmands. Many people are opposed to foie gras because the treatment of the birds is so barbaric.
