Botany and Chicken digestive track question

[ocap]

I am wanting my chickens to plant grass and legume seeds as I move the chicken tractors. Does any seed survive the digestive track of chickens, if yes what type or kind of grass or clover?

I would say no, because the grit in the gizzard breaks it down separating and crushing germ and endosperm of any seed.
