Wow, I didn't know that. Good article.
So I guess the chickens will get the grass. We add their manure to a huge pile of horse manure we let sit, turning a few times. I haven't gotten many weeds from the horse manure. Usually the wheat straw sprouts a fair amount of wheat but it's easy enough to pull or if I remember, I put paper under then if they sprout, they die pretty quickly.
