I am doing a project for school where I have to apply math to the real world. I am going to find the loss/profit from my my chicken egg business. However, I have no idea how many pounds of starter a chick eats before they begin laying. Is there an approximate amount I could use for the equation? To give you an idea, they began free ranging at about 8 weeks of age and have been since. Before that, they only had short visits outside, and were otherwise only eating Flock Raiser. We have several breeds, including brown leghorns, barred rocks, black austrolorps, and easter eggers. I hope that helped give an idea, thank you!
