I'm working on a new "food-producing animals" ordinance for Denver, and as part of that process I'm writing a FAQ for the public. I have a couple of Nigis in my backyard, but there are just a few things I'm having trouble figuring out from my various goat books. Your help would be very much appreciated! All of the questions below are for Nigerian Dwarf and African Pygmy goats, only. How long do goats live, on average? How many years can a doe be productive (do goats go through menopause)? Are there any diseases that goats carry which can be transferred to humans? How common are those diseases? Many thanks!
