Are the bunnies bonded to you, do they trust you yet? Do they trust you enought to eat treats or food from you by hand?
Rabbits kill their young if they are stressed or feel threatened. If they are bonded to you and you really have to touch the kits in an emergency (eg one falls out of the nest), they usually aren't bothered by it if they trust you. Wash your hands first, then cuddle mum so your hands smell of her.
Can you not see the kits without moving them? You just want to see that all they are all wriggling and are all huddled up. If one of them has fallen out of the nest, you will need to put it back as kits can die from getting cold very quickly. If one of them isn't moving, even if it feels cold, you might be able to revive it by gently warming it.
You can tell if mum is feeding them as they will have little round bellies and no wrinkly skin. Google "how to tell if rabbit is feeding babies" to see what to look out for.
If mum stops feeding them, you can feed them with special formula from the vet or pet store. Mum needs a good diet to help her produce milk, you might want to add some extra high in calcium foods like alfalfa hay, kale, parsley.
Once they start moving about and are weaned, you need to keep an eye out for eye infections and upset tummies. They get their gut microbiome from mum peeing and pooing in the nest but they can also get lethal infections from that.
Don't separate the 2 bonded bunnies. Rabbits can die of grief if they lose their bonded partner or are separated from them. If they need to go to the vet overnight, both rabbits should go together.
How big is the hutch? You know rabbits need a lot of space to be able to run and jump and binky? Most hutches on the market aren't big enough.
If you decide to keep 2, a male and female pair usually bond best. Just make sure they are neutered.
