I have a pullet with an "untucked" wing

[cleopatra]

I have a red sex link around 21 weeks old (not laying yet, but soon). She has a wing where the long bottom feathers don't tuck up under the rest of the wing, but hang down. We got her when she was 8 weeks old and noticed it a few weeks later. It gets more noticable as she gets older. It doesn't seem to bother her in any way and she gets up to the top roosts just like the other girls. I was just wondering if anyone has ever seen this before or knows what causes this. Thanks you guys!

Could it be split wing?

I started researching split wing on BYC, and suprisingly, there's not much about it. I'll do some more research on the internet and see what I can come up with. Thanks for pointing me in some kind of direction. I had no idea where to start.
