What finally convinces the animals to fight in the animal farm?

The animals are finally convinced to fight in "Animal Farm" when they witness the brutal treatment and oppression they endure under Mr. Jones and his men. The catalyst for their rebellion comes after a particularly harsh winter and the realization that they are being exploited for the benefit of the humans while receiving little in return. The inspiring vision of a better life, free from human control, and the rallying cry of equality and collective strength ignite their spirit to rise against their oppressors. Ultimately, the animals unite in their shared desire for freedom and a more just society.
