This is the way I build up my herd. I save all of the female goats from the yearlings. I sell all of the males and my breeding male. I bring in a new buck to breed all of them with. This way your male is not related to any of the females.
Goats are easy to raise in hot and cold weather.
A good shelter is all they need to thrive. They get most of the vitamins and minerals they need from the land. You will only need to feed them hay and some type of supplement on a daily basis. They require a minimal investment and a high return on it. Whether you decide to raise a goat for a pet or to raise them for a profit, I know you will enjoy it.
