I give my girls meal worms and then I heard someone mention oatmeal - they loved it. Someone said sunflower seeds - okay would like to try that. Can I give them the ones in the hull? And I guess Unsalted? I don't have many leftovers to give them since I don't cook much. Always give them my leftover salad greens and they like that. They ate tomatoes and cucumbers this summer. What else do you give your chickens?
