What is the earliest age that a rabbit can have a litter?

My sisters kids rabbits have had a new litter of baby rabbits - 2 male and 1 female. At what age should she seperate them so that the new little bunnies don't start doing what comes natural to them?!
Thanks.

Somewhat dependant on the size of the rabbit variety... in the wild, our Eastern Cotton Tailed rabbit here in the U.S., will begin breeding at about 3 to 3 1/2 months for the female and 4 months for the male. The larger varieties of tame rabbits can take as long as 6 or 7 months...

It is best to split them up from three months of age anyway, to avoid any squabbles.

The doe is usually ready to breed at six months and the buck at 7 months.
