When a girl chicken gives birth to a live cock while sucking another cock’s cock.

The reason it’s called rotten plum is because the cock being born is dirty, because the chicken is sucking the cock of another cock while the cock is being born.
Farmer Joe: “Oh no my chicken has rotten plum!”

Chicken: “Too many cocks”

Farmer Joe: “what the fuck. Why’d my chicken talk?”
