In Animal Farm, when the humans have been chased from the farm, what do the animals do?

The first thing the animals did was to destroy many of the things they associated with Jones and human control. They threw nose rings, castrating knives, and chains down a well, and they burned harnesses, halters, and whips into a fire. At that point they simply roamed around the farm, exercising and testing the limits of their newly-won freedom. They could not believe that the the farm was "all their own." In short, the animals began to go about the business of setting up a farm based on the principles of Animalism. The pigs wrote out the Seven Commandments on a barn wall, and they began to plan how to carry out the season's harvest. At the beginning, the animals were happy and optimistic about the future, though the reader begins to notice some evidence that their revolution has already been corrupted--the milk taken from the cows mysteriously vanished, clearly mixed in with the pigs' mash.
