The pigs didn't work, not manual labor anyway. The pigs were the "thinkers" of the farm. That is how they justified getting to eat the apples and milk which Squealer said was brain food.
eat it
One major way mistreatment is used in Animal Farm is that the pigs and dogs get to sleep in an extra hour, get the milk and apples, and are generally favoured over the other animals.
Napoleon offered half a bushel of apples
eat pigs
pick apples in spring on a farm
the pigs got the milk and apples because squealer said that since they were in charge they should get the food which gave them "brain power"
Of course the pigs eat! The pigs eat more than anyone else in Animal Farm, because "All animals are equal, but some Animals are more equal than others".
Squealer saids this to back up Napoleon and Snowball. The pigs actually want those for themselves. He siads it is for their "well-being" to support the others. That they actually dislike milk and apples which we all know thats a lie.
apples
the only kind of fa animal that eats other farm animals are dogs on a farm will eat the chickens and other small animal
