What is stated in the second commandment about four-legged animals or those with wings?

The second commandment in George Orwell's "Animal Farm" states that four-legged friends or those with wings are not to be killed. This emphasizes the idea of camaraderie and solidarity among the animals, asserting that they should regard one another as friends rather than foes. It reflects one of the core principles of the Animalist philosophy introduced by the revolutionary pigs, indicating that all creatures on the farm should support and protect each other against the human oppressor. The notion of "friends" reinforces the bond and mutual respect expected among the animals, underlining the theme of unity against a common enemy.
