I have no doubt your stud threw good babies. She made it sound like that you were breeding soley due to his color , and maybe that was not the case. IN any case, you got good babies, right? That's cool. I am sure you have seen cases where people lose common sense and breed solely for color , when the stud has a poor conformation and end up with a poor result? It does happen, doesn't it?
I am not of a breeding background, but I hear this happens quite a lot. As long as there are people who will buy for color above confo.
