Advice with looking after baby rabbits

[123Holly]

I had a previous thread explaining we had rescued a rabbit who we found out was pregnant. The 7 kits are now 5 days all and all doing well. Mum is being a great mum and looking after them well.
I’m just worried about when they come out the nest. Will mum need to come away at some point?
I have her as an indoor rabbit. She has a pen but we leave the door open mostly and she is litter trained and comes and goes as she pleases. She seems happy and healthy.
Do we need to eventually separate the kits entirely and not let them in with mum? I’ve bought another separate pen. I have a cage and a hitch although I like free roaming house rabbits if possible, and once litter trained.
Any advice welcome.
I will attach pictures!

They don't need to be split from mum until 7-8 weeks old, ideally 8 weeks. Too early will risk their long term health.

If you notice any babies out of the nest, pop them back in. Mum rabbits don't carry their babies. They will be pretty mobile within the next week or so though so you'll need to make sure they're secure and can't get stuck or hurt anywhere as they go on adventures.

You will also need to sex them at 8 weeks and split girls from boys or you'll end up with even more babies!
