Ok I have yet another question lol. I am new to goats and feel a bit confused and overwhelmed. I have 2 yearling Nubian does and a 5 month old mini Nubian buckling. I have been feeding them Purina goat chow and I am clueless to how much I should be feeding them. I would guess Ive been giving them around 1 to 1/2 cups each once a day along with hay. They look great but I would like the does to gain a bit more weight. Should I increase their grain? I don't want them getting diarrhea from too much. Also I'm feeding them Purina goat mineral. Should I not be feeding them this since the goat show already has copper in it?
