Yeah, I've read that it isn't uncommon for hairless females to have issues with abandoning babies, eating them, or lactating issues (not enough or not at all). It seems a lot of hairless breeders recommend breeding a hairless male to het. females or do het. to het.( like how I ended up with hairless).
I hope you have better luck with your hairless!
Btw, the 13 pinks look like all normals and are from a wild type (agouti) mom.
