I know that is a random title lol but I found the thread on Calico very interesting reading and am curious about a gelding that a friend of mine has. He is a solid red chestnut BUT at the top of one leg he has a patch about 2 - 3inches diameter that is palomino. No other colour anywhere on him, so is he secretly a palomino or what?? Mum is a black/brown TB and dad is a dilute Paint (not sure if bucky or pally though). Just curious how it could be explained.
