That's how I keep my does. I do not keep single rabbits, there are just so many benefits in keeping them in pairs. For me, mother -daughter pairs proofed to be the most easy way to do it.
I keep my doelings with mom for about 5-6 months, when I need a replacement I keep the one that get's along with mom best and fits my expectations. Works great for 10 years now.
There is no issue if one has a litter. The other doe always became a great stepmom once the kits got mobile. Only issues occured when they had litters weeks apart, the older kits getting into the other nest. Can be addressed by hutch design, selective barriers and such.
Each of my pairs has 2 hutches, connected with a tunnel. Making their space so that it can be easily temporarily divided helps a lot, to give the doe privacy and direct her to the right nestbox. It isn't really needed to seperate them when one gives birth since the other one keeps away anyway, somewhat confused about what's going on, me think.
I'm a stout advocate for keeping does in pairs, just watching them interact, cooperating and enjoying each others company (at times) makes most of my joy of keeping rabbits. They do work together, like when keeping lookout on the meadow, or grooming off ticks. It makes life easier too, I only have to convince one to go home - the other will follow.
I'm even pretty sure one of the stepmoms started to lactate once the kits got mobile and tried, but that sure is a freak occurance.
