No, but they won't need it for awhileUh-oh. I tried giving grit to my 3 day old chicks in a separate container yesterday and they didn't stop eating it so I took it out after 20 minutes or so.
This morning I put a sprinkle (a couple pinches) of grit on top of their feeder after refilling it. I was changing from paper towel to wood shavings this morning and wanted them to have some grit in case they ate bits of wood. Do you think a sprinkle like that is enough to hurt them?
