They are pretty dang horrible to be honest. These chickens dont get to move let alone get exercise. They are fed cheap gmo grain and soy beans, probably worse stuff as well. And all this is concentrated in the egg.
I would actually advise you not to eat more then a few a day if you cant afford pastured eggs. The amount of omega 6 is just too high. Also remember that organic does not mean anything good when it comes to eggs. Only free range and even then try to buy them from small local farms if possible.
Check craigslist for locals selling eggs, man up and spend the $4 a dozen or invest in a different sort of animal product.
