Nut shells, peanuts, pistaccios, etc. okay for chickens?

[momofthree]

we eat lots of nuts and therefore have lots of shells...i didn't know if the chickens could have fun pecking around on them. i know they wouldn't eat them, but i didn't know if it would keep them busy pecking around or not.

I haven't had chickens for all that long, but I personally don't bother putting shells (unless there is a sunflower seed inside) in with the chickens. I do, however, put them in my wood stove occasionally! My chickens love leftover kitchen scraps, and scratch to peck at. I wouldn't want to get their hopes up that there was something to eat, since when I give them something, it's always yummy!
