It's only dangerous as an aerosol powder in the lungs, like most things powdered.

I do. Usually after a quick whirl in the 'magic bullet' to smash it up.

Yes, it's fine. Pencil lead is graphite which is nothing more than carbon. Won't hurt the chickens at all.

I bake the shells before feeding them back. They can get diseases from bacteria on raw eggshells just like us.
