I saw on another post that it is ok to give treats as long as the chicks have sand or grit to help digest it. I've also seen posts that say not to give treats till they are over a week old, and then I've seen on other posts that there is enough grit in the chick starter that they don't need additional and that if they get too much it can cause problems. I got a bag of grit when I bought all my other supplies, but it just says "chicken grit" on the bag. Is there something special for chicks? Is sand a better fit? Should I wait till I start feeding them treats? Inforation overload! I'm having trouble keeping it all straight. My chicks come on Monday, and I can hardly wait!
