As a Pomeranian Breeder, I'm wondering unless you have the parents, why you would have 3 from the same litter?
Unless you plan to breed (which you cannot breed brother to sister, it is strongly not recommended!) than you should get them all fixed.
Leaving the female with the males she WILL get pregnant during her heat, and She could possibly get pregnant by both of them, and have a multiple sired litter. Not good.
If you are looking to breed, I strongly recommend not keeping litter mates. You could keep the female, and neuter thee males and sell them, and then turn around and but a unrelated male, But if you do not plan on spaying her, or neutering them, I strongly recommend re homing the males.
I do hope you know also that Poms have a very high need for C-sections which will cost you anywhere from $700-$4000 depending if its during vet hours or not. So if you do plan to breed, do your research.
