Are my Rex rabbits to young for a breeding colony?

[Rexyrabs]

Hi everyone, I have a male standard Rex who is a little over a year old and two does (sisters already living together) that are 4 months old. The sisters live in a large hutch next to the male in his hutch, I’m going to build a large enclosure to have them live together as a colony, but will likely have an extension on the enclosure for the male when the does have kits in order to give them a break from breeding.
Anyway, are the does too young to start breeding in your opinions? I have done quite a bit of research and keep getting conflicting info regarding age for doe to start breeding. Any advice and wisdom would be much appreciated. Thank you.

You should wait until they're at least 5.5 months old

I agree with @RabbitsOfTheCreek that it's safer to wait until 5.5-6 months. They can get pregnant before that (and probably will if you introduce the male) but it may compromise their own development.
