The point of the matter is that if you really want to produce that one out of a thousand animals, you NEED to produce a thousand animals to give yourself the odds of that taking place. You can't rely on just luck. If you want to work with triple hets, then it would be wise to plan on producing at least 64 babies from that project. Would you like the odds to be in your favor of producing a sexual pair of them? Then triple that number, at least. Will all of them eat or survive, or should you try to produce more of them, just in case? And that is all just for one project. How many projects do you want to do concurrently? How many such projects do you think you CAN realistically do?
Sorry, but as I learned (and you can see), you just can't play this game seriously unless you throw everything you have into it. To get where you would be with the resources shown in that video starting from scratch would cost you MANY times what I am wanting to sell my business for.
