what is the animals'reaction to the tour the pigs conduct for human behavior?

Chapter 2? The pigs tour the farm, and then they come up with their list of commandments. They've already decided the form house should become a museum, but at this point the other animals haven't figured out that their utopian dream (Old Major's actually) will leave them in a place that is far from Utopia.

The animals reaction is one of disbelief they are shocked that the pigs are now interacting with the enemy and cannot do a thing about it.
