The thought of raising your own chicken for eggs might be intimidating and certainly a lot of work, so if you are more inclined to stick with the traditional grocery store eggs, how can you determine if the eggs you are buying are coming from humanely treated chickens? Well, if you read the labels of eggs it can be confusing. Once again, I was so pleased to read the article "Sorting Through the Claims of the Boastful Egg" in the NY Times on September 16, 2008 because never has buying eggs been more confusing.
As the NY times article states, some claims are regulated by the federal government, state government and some not at all. To ensure that there is truth in labeling, look for the USDA Organic label, USDA Shield or animal care related labels.
Definitions of Labels Claims, as defined by the agriculture department (resource NY Times):
Cage Free -- chickens kept out of cages with access to continuous food and water, doesn't necessarily have access to the outdoors.
Free Range --meets cage free standards, must have access to the outdoors, unless there’s a health risk present. There are no standards, though, for what that outdoor area must be like. (A concrete lot could do.)
Pasture Raised -- no regulation on this term. It implies that hens got at least part of their food from greens and bugs. Like other pasture raised animals, some studies suggest that pasture-raised eggs have more nutrients, in particular Omega 3 -- fatty acids.
As far as animal care labels, most of them have requirements on farm density, reducing feed to increase egg production, space, feed, etc.
"Animal Welfare Approved" a label by the America Welfare Institute. This label requires is given to independent farmers and has strict standards for the humane treatment of animals. The great news, is that Animal Welfare Approved foods are available at these stores/farms in Minnesota. According to the NY Times article, "flocks can have no more than 500 birds, and chickens over 4 weeks old must be able to spend all their time outside on pesticide-free pasture with a variety of vegetation. They must have access to dust baths and cannot have their beaks trimmed (a practice on crowded egg farms) or be fed animal byproducts."
The Humane Farm Animal Care, created the "Certified Humane Raised and Handled" and is audited every year by the Department of Agriculture. Chickens are kept cage free, although not necessarily outdoors.American Humane Association created a voluntary label similar to the Certified Humane Raise and Handled (above).
Organic chickens are cage free and are able to go outdoors, although there is no defined time. They are not allowed to be given antibiotics. They are free fed from animal byproducts which is made from crops grown without chemical pesticides, fertilizers, etc. If eggs are titled "organic" without the seal, then they may be regulated by the state and don't necessarily meet the same standards.
There is a lot of information as it relates to labeling. I encourage, if you can to buy "farm fresh" eggs where you know the eggs are coming from a small, independent grass fed farm. As listed above, you can find local listing of animal welfare approved eggs here!
