I'm sseing all of these posts about people feeding their new chicks yogurt and oatmeal and other things. I thought the food from the feed store was sufficient? Do I need to supplement with other things or will that be fine? I want my chickens to have the best life possible, but I don't want to spend a fortune on them. We are going to be eating them one day...well some of them. We are getting a nice mix of strictly layers, and some dual use birds too. I even want to find some big ol' meat birds, just cause they are huge and awesome! What do you recommend starting my chicks off with?
