That does look funny... hmm I'm not really sure on this one I've never seen one like that before. I would be interested to see her with an udder and see if that teat keeps pointing backwards or not. If it does that would probably be pretty hard for kids to get a hold of.
They appear to possibly have double orifices. If they are it is a DQ for show but kids will do fine on them.
I have one like this, her teats just didn't look right when she was young. She has had several sets of trips & quads & hasn't passed it on.
Some of my girls teats go every which way but straight down; almost impossible to hit a milk bucket but kids never have a problem.
Okay guys, I tried my best to get an up close pic. It's not great but I think you can see the orffice well enough. She only has one! (From what I can tell. And I pray and hope) but she does have a small nub teat growing beside it. Maybe the reason for the odd growing?
