I understand where you're coming from, I'm in the same place. It doesn't matter to me that grass fed beef can be had by the half animal for $4/pound because I don't have a deep freezer and buying huge quantities doesn't make much sense when we could get word at any time that we have two weeks to pack up and move to another state (it's happened to us before and I had to give away or toss a ton of food).
I buy all conventional meat at the grocery store, conventional hormone/antibiotic free milk at the grocery store, and I buy eggs from pasture raised chickens at the farmers market. I could buy raw milk, grass fed beef, pastured chicken, and pastured pork but it would cost an arm and a leg to buy in small quantities and I would have to drive two hours each way to pick it up - not going to happen with a bunch of little ones in tow, not to mention the cost of gas.
chicken: my understanding is that hormones and antibiotics are not allowed to be used on meat chickens, I do worry about pesticide from their feed getting into the fat so I buy lean cuts, like skinless breasts and add olive or coconut oil while cooking; I also try to avoid chicken with "retained broth", tyson usually has it on the package that their meat contains it
pork: we only have conventional generic pork at the on base grocery store (the nearest off base grocery store other than walmart is a 30 minute drive), we don't eat tons of pork so I don't stress about it, I just buy leaner cuts and trim excess fat
beef: we have two options, generic beef or laura's natural ground beef for twice the price. I buy the generic stuff. When I get ground beef I buy 97% lean and I look for leaner steaks and roasts. Many beef cows are raised on grass and "grain finished" on a feedlot, while this is not ideal it still means that the cow was only eating nasty feed for the last few weeks or months so I don't have a problem eating the beef.
fish/seafood: I buy only wild caught but I don't worry about the type of fish (unless I happen to the pregnant at the time, in which case I avoid bigger species such as shark and swordfish to lower my mercury intake).
other meats: We eat turkey only occasionally and I try to get birds that haven't had anything injected for flavor or moisture. I really like lamb and the lamb I can get is great and grass fed but it comes from down under so it's super expensive and is a rare treat. I've been getting into cornish game hens, I have no idea if they'er better for you but I can't imagine they're worse than chicken. We used to eat buffalo all the time when we lived on the high plains because it was cheaper than beef but it's difficult to find here and expensive when I do find it.
