I was under the impression that once they were outside and could eat dirt/rocks whatever that I didn't need to supply them with grit anymore. When they were still in the brooder and I gave them a treat here or there I made sure they had grit as they didn't have access to anything. But I have seen many people on sites that I am on talking about supplying their chickens with grit. These chickens either have access to a run or some free range. Mine have a large run with dirt and I use grass clippings in there. Should I still be giving them grit on the side? I just give them their chick feed (they are 13 weeks), a mealworm treat here and there, and fruit once or twice a week. They also come out to free range for a bit if I am outside with them.
