The only thing I would suggest is make sure you are 150% certain it is the male you have taken out.
Theres nothing really you can do now, rub your hands in the does bedding before doing anything and just have a little peek at the nest but don't touch the babies yet. Mum will feed the babies only once a day, so don't worry if you think she's not feeding them.
Check the nest everyday just to make sure they are all wriggling around. Usually at about 10 days they eyes start to open and you can start to handle them when they come out of the nest themselves, just make sure you always rub your hands with mums bedding.
Make sure mummy bunny has plenty of hay and veg and pellets, you can give her unlimited food at the moment as she needs all her energy to feed the babies, just don't suddenly increase her food, increase gradually over a few days if she's been on normal rations.
The babies can stay with mum until about 8 weeks, then they need to be seperated into males and females (easier said than done!) You need to keep an eye on the babies when they are weaning to make sure they can cope without mum and rehome them at about 10 - 12 weeks (unless you keep them!)
It might be an idea to have daddy bunny castrated asap so he can be bonded back with mum when babies are weaned, as castration will take 8 weeks at least to have the full effect.
Hope this helps you :wave:
