Give two ways in which Napoleon is turning into a dictator?

Napoleon appears in public less and less, and when he does, six fierce dogs act as his guards. As there is need for more grain, he has Mr. Whymper arrange a contract to sell four hundred eggs per week. 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, supposedly of coccidiosis, during the five-day strike, after which the hens surrender.
