Another place you can check out is the local farm adviser's office. They will have bulletins on goats and other livestock meant for 4H projects. These publications are very helpful and they are free or available at very low cost. If they don't have what you want in stock they will have a list of what is available and you can order what you want. The University of Pennsylvania used to have correspondence courses on various classes of livestock. I got the ones they had on poultry, dairy goats, and home butchering and processing of meats. I don't know if the still offer these, but it is worth checking out. The courses were very inexpensive and the written materials were well written and informative. Just write the university and ask.
