I've learned this year that the roan shows up after the first foal coat is shed. Not sure why or how that works, but it was interesting learning, LOL.
I do see that in our ONE roan mares' foals (however - there is also a grey gene involved in those foals' sires, so...it's REALLY confusing!). If she is not pregnant, will be breeding her when she comes into heat - want a bay roan pinto foal.
Too funny story about Cooper! LOVE it.
I have two ponies that are blind in their left eye. One went that way with fibroid development with age (talking with a vet now to see if it's tied into silver dapple coloring - but seems would have happened a lot earlier if that was the case. She's 24 this year), the gelding had an eye injury when he was a yearling and the eye slowly lost fluid until his eyesight is now gone and eye is flat. Bit rides and drives and seems to do ok since losing full sight in that eye. Ranger has been spooky since our move here, but will be working with him more and starting to drive him this summer. He'd make a nice riding "mini", too, as he's a pretty stout 38" tall boy... when muscled/conditioned, I expect he'll be pretty close to 400 #s.
