I have 3 one year old pygmy Nigerian goats. I am very new to goats. I have been feeding them plenty of alfalfa pellets and a little sweet feed(every couple of days). I also cut leafy brush(not much) about every day or two and toss it in to them. I will be able to allow them to range in grown up brush soon, but for a few weeks they are having to be penned in a 15x25 area with little to no roughage. Should I be feeding them any thing else in the interim? I am working on a pen with roughage and should be able to get them in it in a week or two.
