Yeah, they're all going through their "Spring Moult" as I call it. Their dark winter guard hairs shed off first and that leaves an almost white, woolly undercoat, and that sheds off next, leaving a short, medium gray summer coat which gradually lightens as the weather gets warmer. One thing about roans, they're never the same color on two different days.
Yeah I expect you will get some teasing for awhile:’) Enjoyed the pics.
