Of course there is a movie -

Poultrygeist: Night of the Chicken Dead - Zombified chickens attempt to kill the fast-food workers that cook them in a restaurant built on an ancient burial ground.

Believe me. If someone fell down in a chicken yard and were incapacitated, chickens would.

Those little beasties do not give the first fuck, and they are ruthless.

@BufftonBeotch You mean that they don’t give a cluck?

Yeah, chickens are ruthless. My sister has some living on her regenerating forest and they take out the mice and rats no problem.

My niece saw them in action, she found it quite traumatic.

@Zealandia Not sure where you are but in the US we have certain eggs cases marked as "from vegetarian chickens."
I have had to tell people that means a chicken who has never seen the sun or felt the grass and is probably de-beaked and in a cage where they have never stood up.

I believe chicken is soul food.

Of course, we all have the original sin, don't you know that? Now kneel and do the chicken dance.
