What can you call them? Well, you can call them cute!
Seriously, though, the buck is a dove satin (maybe also a poor angora--it's hard to tell). The female is a black marked (sometimes called "broken" although that is not exactly accurate).
The buck is a/a p/p S/S (black + pink eyes, carrying no spotting).
The female is a/a P/P s/s (black + spotting, carrying no pink eyes).
All the babies are black because the only genes the parents shared in common were a/a (black). If you breed the parents again, the babies will all be black again.
If you breed the parents to the children, or the children to each other, you'll get a little bit more variety.
