So this past week I picked up a handful of new chickens. All different kinds of breeds. I saw at the barn they feed the chickens the same food I feed mine. My wife and I cracked one open and looked, and it looks fine. The shell is not as hard as the eggs from our other chickens. But I figure it might be since mine are outside, and these chickens were kept inside. Am I just being to cautious? Should I just eat and enjoy them?
