We are brand new to chickens. Looking to cut feeding costs. Currently have 7 Barred rock hens, 16 guineas and 26 Black Australorp chicks coming along. The adult birds free range during the day, but will be cooped up more during the coming winter. Any good sources to buy bulk quantities of feed? Is it any cheaper to make your own? Currently just buying bags of food at the local Atwoods and supplementing a bit with garden and fruit scraps. Any help is appreciated! Thanks!
