I bought a chestnut mare from a friend of mine that owns a bay stallion. He swears that one of the results of breeding these two horses was a dun. The problem is that the baby died at three days old, so there is no way to prove this. But the stallion owner is positive that the baby was a dun. Now, I have bred this mare to this stallion for three years in a row (she is due with the third sometime in may) and the two foals from the years before are both bays. My question is: is it at all possible, though it might be very rare, for a bay crossed with a chestnut to produce a dun baby? Any input would be very appreciated.
I bet the baby just had alot of counter shading that would have shed off if it had lived longer. Alot of babies have really distinct dorsals that are just counter shading and it sheds with their foal coat. It is not possible for two non dun parents to have a dun. It is dominant and will be expressed if it is there.
That is exactly what I have said the whole time, but the stud owner just insists that the baby was a dun. Anyway, it is good to know that someone else agrees with me. Thanks
I currently have a filly out of two sorrels. I'd swear that she's a red dun! I would put money down on it! But, knowing that both parents were sorrel, I know that it's countershading. Unfortunately!
