What is the point of a breeding farm on howrse the one you can create when you reach 3 karma points and what can it be used for

The point is tthat you choose a breed, probably best to choose one that you have more of, and add all the horses of that breed to it. e.g. My breeding farm was for Arabians, I would add all my arabians to it. It can separate the breed from others, so it is easy to find. Hope it helps. Add me I am RisingStar on howrse.
