Do you breed or use artificial insemination for your animals? What's the pros and cons? I would think that if you didn't have the male animal you would have to "rent" one. Is it cheaper than artificial insemination?
We used to breed goats and sheep. We always kept males, and never used AI. I have some friends that have used it. AI can be especially useful if you want to add certain genetics to your herd without increasing the number of male animals that you have to keep.
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.
