Sure i'll take your word for it. I was basically joking about the liquid part

. The point is, natural licks are hardly the most efficient way for deer to get micronutrients, however, it's been proven in research that natural licks make a difference so by default anyway they can get minerals makes a difference. If you want to go buy granular..good for you. All I'm saying is your not wrong if you want to use blocks instead (I do).
