diet is a huge factor, yes. i keep free range chickens that eat nothing but forage. still taste like chicken though. i imagine that activity level changes the taste of things as well. wild pig and domestic pig taste very noticeably different, even when they eat the same diet, which means that other factors like moving and environmental stress changes the flavor of their meat. domestic ducks and geese are a much more mild taste with less natural oil than their wild counterparts for another example.
