a lot of them are. cage free is probably the least helpful, because that just means they're not confined to individual cases, they could still be (and usually are) cramped as .
free range and pasture free are more useful. they also are a bit more expensive. ive been buying pasture free eggs, but i think the best thing you can do is find local small farms and see where they sell their products. and even then i think the actual government regulation for those are so fringe... but there are some activist groups that certify, but again, those vary in importance and you have to be knowledgeable on whether or not its just some front for the food industry
