we have a brown jack but he looks like he has sorrel highlights on his chest when he is all shed out, and on his ears... 2 grey-spotted girls, 4 grey girls (and they are all related but also different shades of grey!), 1 chocolate girl (breeder said black but to me she is chocolate...) and my new jack is a charcoal spot. can't wait to see what mixing them up will do! the jennet we lost was a silver grey, very light and kinda splotchy, different shades of grey... with a white blaze. very unusual from what i have seen...
