Dh wants me to have a full list of exactly what it will cost to keep chickens. I am having a lot of trouble finding out how much their feed will cost. I want 10 laying hens and I think I want an assortment of brown egg layers. They will have a run and I plan to let them free range a few hours a day. We have 8 acres of land. Just a ballpark guess is what I'm after. I looked it up and laying feed in our area is $9.50 for 40 pound bag.
