I didn't get a good screen grab, but this guy had a definite skunk tail: Hip 3544, Dark Bay or Brown Colt -- Purim x Sharp Tradition by Sharpen Up (GB)

And here's a bay with a grey tail: Hip 2992, Bay Colt -- English Channel x J. D. Flowers by Dixieland Band
Doesn't gray usually become obvious long before they are yearlings? All the gray babies I've ever seen start looking gray as soon as they start shedding their foal coats...is it common for them to turn gray slowly over years?
A woman needs 2 animals in her life-the horse of her dreams, and a jackass to pay for it!
Some do. I saw several at this sale that I wasn't even totally sure WERE gray. In fact I find it rare that a yearling have lost much color yet. Be showing gray, yes, but be lightening yet, not really.
