Does anyone know where I can find a chart that breaks down roughly how much feed chicks tend to go through each week? I know that some of it will depend on the brand of feed, the protein percentage, breed of chicks, etc. I'm not looking for exacts, just estimates. The chicks will be on starter and are dual purpose/laying breeds (Leghorns, Easter Eggers, Rhode Islands, Barred Rocks). Right now they are two weeks old and there are 100 of them. Any clue as to how much feed they may go through to grow for another month? One bag? Four bags?
