How did animals on the other farms react to the rebellion on Animal Farm?

In Chapter Four, we learn that news of the Rebellion has spread to many other farms, thanks to Snowball’s and Napoleon’s pigeon messengers. Meanwhile, in the human world, Mr. Jones tells other farmers about the Rebellion. The fear of similar revolutions unites the owners of the farms adjacent to Animal Farm, even though they dislike one another. Easy-going Mr. Pilkington (of large, neglected Foxwood) and hard-nosed Mr. Frederick (of small, better-kept Pinchfield) spread rumors to discourage their animals from turning against them. They say that the animals on Manor Farm are starving. When this claim turns out to be clearly untrue, they claim that the animals are cannibals who practice all kinds of wickedness.

Despite the farmers’ efforts to subdue ideas of rebellion, their animals begin lashing out against them. The animals resist the farmers’ orders. They also adopt the infuriating habit of singing “Beasts of England.”
