Sorry for not posting any responses until now. I live in the boonies and only have satellite internet. We had storms yesterday and storms + satellite internet = no service.
The son in law's stallion was bred to two different mares, but they were both sorrels. They each had a sorrel foal and then the mare my son in law bought also had the bay paint, after having the sorrel paint.
As for the foals out of my mare - I never saw them and am having to rely on what the previous owner tells me. She's not very knowledgeable about horses, though she'd never admit it. The previous colts could have been pretty much anything - the previous owner thought my old mare was a buckskin, and she was a classic bay!
I am quite sure Dancer is pregnant - we've had her nearly a year now - brought her home 07/11/09. Son in law turned the stallion in with her about a week later, and they put on quite a show. She's starting to make a little bit of a bag and her belly has dropped. You can also see the foal kick the tar out of her once in a while. She's probably due in 2-3 weeks. Or a little longer. I don't know a lot about pregnant mares and never claimed to.
As for riding her,
Plain Old Dee, horses Dancer and Rain I believe in dragons, unicorns, good men and other mythical creatures!
