It's usually cheaper to rent a stud than it is to go with artificial insemination. Goats - if you're looking to increase your milk supply, and you aren't intending to add to your herd, then renting a stud is the easiest way to go. Sell the offspring when it's old enough and continue milking its mother. Chickens - If you don't want a rooster, I'd buy fertilized eggs or chicks because they're affordable.
