There are such things as heritage and forager breeds, not to mention dual purpose breeds. The industrial meat birds are the only ones that really have the issues you describe. Look into Kosher Kings or Freedom Rangers and you'll see they don't have those problems. As others have mentioned, raising them yourself is much more humane than buying it in the store. The only reason it would be more sad is because the suffering of the birds in the store is hidden from you.
