Hi, I just purchased 2 - 9 week old wethers. I am feeding them King Brand Pygmy Goat Complete. I need clarification as to how much I feed them. I was told 1/3-1/2 cups. Is that per goat or total for both of them. I am new to goats. I am also feeding them alfalfa and they are grazing in our yard. I appreciate any help especially with wethers. I want to prevent kidney stones. Thanks.
