What are the themes of chapter 7 of Animal Farm?

Fear and manipulation are themes in this chapter. Napoleon appears in public less and less, and when he does, six fierce dogs act as his guards. The hens rebel by laying their eggs in the rafters so that the eggs smash on the floor. Napoleon stops the hens’ rations and makes feeding a hen punishable by death: nine hens die. Squealer makes up a story that Napoleon cried, “Death to Humanity!” during the battle and bit Mr. Jones in the leg.
