In the July/August 08 Countryside Magazine (pg 12) someone wrote in about how it's cheaper to raise your own eggs (no brainer there). He also says: "I have goats now, and layer feed has too much copper in it so the chickens get goat ration, cracked corn and sweet feed. The goat has about the same protein, and I am getting the same number of eggs this winter without a light in the henhouse as I have had in previous years with a light on." Has anyone ever heard of that before - that layer feed is copper heavy? That you give chickens goat ration and they lay through the winter?
