Pack of 3 leopard appaloosa in little Creek river how rare can they be?

Herd of 3 leopard skin appaloosa with a blanket , also a standerbred buckskin and dapple grey thoughbred with some Morgan's... Either this spot is money or not so rare. I'm on chapter 2, I've already found more than one of both have a few spotted, leopard and blanket in stable...think I'm going well some of not all. Right now debating thinking I'm taming the grey dapple for my grun mustang. My other horse is black and white Hungarian halfbred and had this one since early on but stat wise , and dapple grey looks good over mustang. Hungarian is a war already anyway. Just Incase anyone is looking rarer horse, apparently they spawn at little Creek river. Just watch out for the wolves are spread around. Good herbs and hunting to. Gl all
