How does the behavior of the pigs foreshadow their eventual leadership positions? (The pigs have secretly taught themselves to read and write during the past three months. They rename the farm and reduce the principles of Animalism to seven commandments, which Snowball writes on the barn wall. The pigs milk the cows, who are about to burst.

When Napoleon sends the rest of the animals off, led by Snowball, to harvest the hay, he stays behind and drinks the milk. No one notices, but the pigs are already proving the contrary to what they preach, all animals are not equal.)
