What sign is there at the end of chapter 2 that Animal Farm might not be such a utopia after all?

There was a situation with the milk disappearing. Later at the end, it is revealed that the pigs took the milk. This is important because it shows that the pigs  are not sharing everything with the rest of the animal which goes against their principles and because it shows a tendency to behave as Jones had behaved.
