If you love yolks, like you say, they should be good. I'm unaware of exactly how "safe" they are, if there is any authentic study as to the amounts of AA, and exactly how a 'natural' product like an egg can be tweaked to such standards.
I've found the omega-enriched eggs cost three times what regular eggs do. I'd be using half as many if I ate the yolks, but...you do the math.
I've become accustomed to eating only egg whites (or sometimes egg substitute). I have eaten omega-enriched eggs and have found them to be of superiority quality, but, personally, not worth paying triple.
OK, so I did some research and found the following article, which will teach you more than anyone needs or wants to know about egg production. (Who knew chia seeds are good for anything other than those silly ceramic "pets" ?!) :roll:
