This is my first year with chicks. They're are currently about 3 1/2 weeks old. So far they have been solely eating chick starter. I want to start giving them the occasional veggie scrap or "treat". I have already purchased chick grit. But my question is should I just leave a small bowl of grit in their cage for them to use as they please? Should I sprinkle the veggie scrap with grit? Or should I just put some grit on a small bowl next to the veggie scraps and then remove when they're done with the veggies? Or just leave it in all the time? Seems like a silly question to me but I can't seem to find a clear answer. I just want to do what is right. Help!! Thank you.
