I have a son who wont eat our freshly layed chicken eggs! He says that unlike store bought eggs, we havent certified whether or not they are fit for human consumption. In reality, I guess he does have a point of concern. Just how "Do" we know if our eggs would pass a USDA certification test? Do they screen out the bad ones or what? Is there some kind of light or equipment that they use? If so, is it available to us hobby chicken farmers and locals?
