Obviously chickens eat dirt deliberately for grit, but can too much dirt be an issue? I’m raising a blind chick (she’s six weeks old now) and she can’t tell the difference between her chick starter and dirt. She seriously will just chow down on dirt quite happily. She knows how to eat her chick starter– she’s memorised where the bowl is and knows that when she’s standing on the rim she can peck. But nonetheless she’s convinced that dirt holds nutritional value as well.
