I am going to be getting 6 chicks from my local feed store in the spring. The chicks will be from MMM, and they will be a few days old when I pick them up. My question is: Do I need to give the little peeps Grogel once I bring them home? (The feed store is only a five minute drive from my house.) If I need it, where can I get it? What are the chances that my feed store will have it?
