In a hypothetical scenario where a cat and a mother hen engage in a fight, it would likely involve the cat as the aggressor and the mother hen trying to protect her chicks.
The cat might try to pounce on the hen or swipe at her with its claws, while the mother hen would use her beak and wings to peck and flap in defense.
It's important to note that such a situation is not ideal and should be avoided, as animals should be treated with care and not encouraged to fight.
