I've searched the forums and can't seem to find the answer. When can I offer grit to our chicks on a free choice basis? Our chicks are currently 4 weeks old and we have been sprinkling grit on their food. We just built a new wall hanging feeder and have an area to offer oyster shell and grit in their own bins. We know we don't offer them oyster shells until they are ready to start laying, but when can we give the grit as free choice? Will they go crazy and just eat all of the grit and not eat their food or are they old enough to self regulate?
