Grass-fed beef is very similar to wild game meat, although the levels of omega 3 still tend to be a bit lower.
About eggs, I heard on the Weston Price site that the phytoestrogen from soy can be in the egg, and most chickens are fed soy... How many birds do you see eating grains and legumes? They eat insects, seeds, small fruits... Insects are very high in omega 3, and "natural" eggs should be the real omega 3 eggs.
In my opinion you should keep eating raw animal food.
