Hi I'm new to the chicken world I am getting my chickens in two weeks and I'm trying to figure out what to feed them. While they are chicks I plan on feeding them purina starter but I want to keep cost down and maybe make the feed myself. I have done a lot of research but I cant find out what is a total supplement for the chickens?? If I start sprouting grains for them do I still need to fed them something else? Of course I want happy healthy chickens and they are going to be raised for eggs and as pets not meat production. But do I still need to feed them purina? I am planning on getting a lot of different seeds, grains, and beans to sprout will that be enough with them free ranging on my 5 acres In the country and with fresh fruit and vege scraps?
