I agree if you are wanting them as pets for your children they should be wethered. But not all bucks turn out to be vicious and mean. I have owned several bucks and not one of them ever tried to harm me. Most of them were actually quite sweet. I always treat my bucks as pets, just not so much while they are in rut because they stink so bad and they are so preoccupied at that time that they don't want any attention anyways. And like I said earlier, I currently have two bucks. My alpha male is four years old and one of the SWEETEST goats I have ever owned. He loves to be petted and scratched and has no fear of humans. He has never once tried to attack anyone. I'm not saying that all bucks are sweet but I also want you to know that not all are mean either. In the end it is a decision you will have to make. Another good point is that you are wanting to breed fainting goats...in that case I would also wether them. Dont start your herd off with a buck that isn't what you are aiming for for your herd. If you want a fainting goat herd I would wether these boys and get a fainting buck when your ready.
