I have heard also that horses who will turn grey are often born the "adult" version of a color. What I mean by that is that most often when a black or bay horse is born, their dark points are light in their foal coat for a while (making them look like the may even carry a silver gene when they do not). What I have heard is that instead of being born with a usual foal coat color, a horse with the greying gene would be born with the dark point already darkened. For example, instaed of a black horse being born that fuzzy grey color, they are born dark right from the start. Has anybody experienced this to be true?
