$250 isn't a bad deal on two females coming up on breeding size.
Proven females, that would be an "each" price and proven het pieds would be double that easily.
A lot of time and rats go into a breeding size female.
The short-cut on your male pied, I don't know what size your other girls are BUT I would get these two and either make your own KNOWN 100% hets with one and pair one of your other males with the other one.
Then again I would also pair the pied and the bee for hets too and make it worth the grow out time
