We're finishing our coop setup, and everything's going great. Pretty soon, it'll be time to order our very first chicks! But I have a question... Our coop would comfortably hold 12-13 chickens. So should I purchase 12-13 chicks, or order more, assuming that some will die before they reach "coop age"? I have no idea what to expect. I'll be ordering them from Murray-McMurray Hatchery--I hear good things about them and their chicks. But given the frailty of chicks and our complete inexperience, I'm guessing that we'll lose some. What's a typical survival rate? Any wisdom? I appreciate your help!
