I don't know much about breeding - but just looked on google and found this answer from allexperts

"Yes, they can.

In fact, rabbits normally do have a "multiple births" That simply means that more than one fetus is born from a pregnant animal. Rarely does a rabbit only have one kit (baby rabbit).
A multiple birth includes more than just twins though, it can also include triplets, quadruplets, etc.
Just as with humans, the resulting baby rabbits can be also dizygotic (fraternal) or monozygotic (identical)."

I learned something new too! Thanks gravehearted!

Can you post pics of the twins?? That must be so cute!
