Yes, if it's not in the grit already add some crushed oyster shell to it. All my birds get grit, I usually buy the Red Cross Gray Grit as it comes with the oyster shell already in it.
Anyway, as long as they have clean water, good feed, grit and a safe place to live, they will eventually get down to business and hatch some babies for you.
