Will the boob hatch okay?

[Lolo76]

I have a clutch currently incubating (mojave or pastel x normal), and it consists of 4 perfect eggs and 1 small "boob" egg. They're now 3 weeks into incubation, and so far it's looking good... shows good veins, no mold, and I think I even saw a little movement in there. Whaddya think? Is he/she going to hatch okay, and if so, will it most likely be a tiny snake?

P.S. The other eggs look great too, with strong veins and slight movements. One has flattened slightly, since it's at the top of the pyramid, and thus not getting much substrate - but not flat enough to be worried.

Here's the boobie...
