This topic intrigued me so I went out to the barn and did a "penis check".
I was interested because I have a meat rabbit in a cull carrier right now. He's being culled because he has a split penis. In fact, I thought he was a she all the way up until he was 5 months old! Embarassing for someone who is not a newbie but it's true. I was packing up rabbits to bring to a lady who wanted a doe. One last check (ocd?) gave me a real shock - that it was actually a buck. I brought the rabbits to her anyway to show her (and apologize). It was she that pointed out the reason for the confusion was a split penis. We both agreed but got a judge's opinion and he agreed that while it was minor, it was, in fact, split.
My first thoughts were when I saw your photo were, yes, "that is a well defined line" and "those lines are normal on bucks, though, they are usually not so pronounced in my experience". IMO, *judging by the photo*, I'd say this is definitely not a split penis.
I was curious to compare my split p guy to the other TWELVE bucks, of three different breeds, I've got in my barn right now. If I were to go by your photo, 9 of the twelve bucks I examined have split penises. Of course, I know that is not so. Only one does and I can see the difference between his "minor" split and their normal lines down the underside of their penises. The 3 rabbits that showed no or little sign of lines were young bucks around the age of 7 months old (all the same age, different litters/breeds).
I also had the "privilege" of examining two bucks fully extended. These two silly boys like me and are always happy to oblige. So, I just picked them up and viola'!
Well, I found out that Kagee is exactly correct in her description of the normal, fully extended shaft.
There are lines up at the first 1/4 - 1/2 inch of the shaft but not beyond that.
The difference between my normal bucks and the buck with the minor split penis is that the split p buck's line looks abnormal. In his case, his line is staight for 1/4 inch and then there is an deviation from the straight line. To be more specific, it looks like he tore and then healed. It is not smooth, it looks indented, it is not straight. Yes, it is minor but it is visible and not something that can be easily mistaken for something else.
One *might* think "Wonder just has a bunch of bucks with split p's because it's bred into her line". No, these penis shaft lines are on all but young bucks and across three different breeds and 5 breed lines.
I have one buck in particular, who has low color %. He is also an extremely nice buck. The judges often want to place him as BOB so they hem and haw over his color %. Deciding that they can consider him 10%, they then go over him with a fine toothed comb to look for any other DQ they could find. Trust me, this boy does not have a split p else it would have been picked up on and he looks exactly like all my other bucks with normal penises. They've got lines. Plain and simple. If yours has a split p, it will look "torn" or it will open up wide.
That said, I read that you got hands on second opinions. An exhibitor tried to open it up ? (
) I guess if they were able to do it and you saw it plain as day, well....
. That's a bummer. I was hoping it was a normal p. It looks absolutely, 100% normal in the photo.
