Rabbits build a nest for their babies using fur they pull from their chest area, but this happens before they give birth.
It's impossible to say when a rabbit will give birth after pulling out its fur, as the gestation period for rabbits is around 30 days.
It's important to remember that rabbits are delicate creatures and require proper care. If you have a pregnant rabbit, please consult with a veterinarian for advice on how to best care for her and her babies.
