Are free range eggs better than those from the supermarket? According the an article in Motherearth News, yes they are.
I am not 100% sold on the results of this study. The results show that the pasture raised chicken eggs were much healthier for you than store bought eggs. It apparently consisted of eggs from 14 different flocks from around the states which were compared to the USDA results for eggs. I think that the sample group was much too small to really represent the correct results.
I do know how I have found my home raised chicken eggs when compared to store bought eggs. Here is a picture of some French toast (yes, I know it isn’t real French toast, yet it is good enough for us) we whipped up on the weekend when we had a glut of eggs from our girls. One of the pieces toast appears bright yellow, this was the home grown egg. The other egg was a store bought one, and you can see that the colour is washed out. The taste difference was very obvious too, with the home grown egg having much more flavour with layers to the taste. The store bought egg tasted bland when compared to the home grown egg, it just tasted of egg with no subtle flavor.
I suspect much of the additional flavor comes from the diet of the chicken. I had a friend who recommended feeding chickens chilli (which I have not done, and I am not sure it would be a good idea).. he swore that the eggs had a hint of chilli in them and made excellent meals.
So if you ever get the chance to try one I would recommend it. I am sure if you try you could find a place near you which sells home made freerange eggs.
