Perhaps not an issue but my concern would be what happens if the foal takes on more pony characteristics and is too small to nurse. Is that a possible risk factor?[/QUOTE]
I don’t think a foal could end up being that tiny…unless it was a Mini cross. A friend bred her 16.0 HH Hanoverian mare to our 12.2 HH pony stallion. Vet missed two embryos on the ultrasound and mare ended up having a tiny set of twin fillies. They had no problems reaching up and grabbing on to the milk bar.
