Here is another. http://www.rodgerscattleco.com/sires.html
They both look great. One has a feather neck and one does not. There are some other color differences but I was fooled at first.
Both of these are Hereford marked bulls but I didnt clue in there were two until I started looking closer at them. I am sure it was not intended but it could get confusing if you are not paying attention. Am I mistaken or is there more to this?
