Why are birds included in animalism's maximwhat do ha nds represent In animal farm?

In George Orwell's "Animal Farm," birds are included in the maxim of animalism to emphasize that all animals, regardless of their species, should be treated equally and share in the benefits of their collective efforts. The inclusion of birds reflects the broader theme of unity among all animals in the fight against oppression. Hands, on the other hand, symbolize human labor and the exploitation that comes with it; in the context of the farm, they represent the humans' control over the animals and their work, reinforcing the idea that animals must reclaim their labor for their own benefit.
