When a pregnant Rabbit has already started to build her nest before been given a proper nesting box should you transfer the already built nest into the box or should you leave her to finish?

It's best to leave the pregnant rabbit to finish building her nest in her chosen location. Transferring the nest can stress her and disrupt her maternal instincts, potentially leading to complications. Providing a proper nesting box nearby can offer her an alternative without interfering with her process. However, ensure the box is available and accessible for her to move to if she chooses.
