I have my first batch of 15 Australorp chicks in the brooder right now. I plan to keep about 6-7 chickens for eggs. They sure seem to be burning their way through the first 25lb bag of crumbles. How many pounds of feed does an average chicken go through in one week? Or I guess maybe I should ask how many 50lb bags will I need to buy in a month for 6 chickens?
