How do I avoid buying these?
Generally go for organic if you can (but you can caught out doing this too because of false advertising and general skullduggery on behalf of the producers).
Free range alone might not be any better than normal eggs either, as to qualify your eggs as "free range" all you have to do is use battery hens but just expose them to a period of natural light each day. "Free range" hens can also be fed the same chemical and GMO crap as battery hens.
Your best approach if possible would be to buy from a farmers market or directly from a farmer. You'll know a good egg by the yolk - it should be much more of an orange colour. But even this is not a certainty as you will now get producers feeding their hens colour additives to get that look.
All this might seem a bit over the top but the fact is that a hen produces an egg from the resources and nutrients it gets in its diet. If its diet is hormones, chemicals and cheap GMO crops, then that's what you get in the egg. If however, its diet consists of natural greens and insects as it should, you get an egg yolk full of anti-oxidants and omega-3's.
