I bought granite for my chickens, so that I could feed them treats and flax seed, and a big can full of dried mealworms, but, when I opened the bag of grit, i saw these chunks that seemed a little... monstrous for a tiny chick, so I checked the bag and it said to feed grit beginning at eight weeks of age. Can a chick younger than eight weeks eat mealworms and flax seed? Do I need to try to find chick sized granite, or do I have to wait till eight weeks to feed them treats? What treats can the little ones have? Besides yogurt... I know about yogurt.
