If there is ANY uncertainty about her due date, I would give her a nest box. Worst case scenario, she is not ready and will soil it, in which case you will have small extra cleaning job. If you don't give it to her, and she is ready, she will kindle on the wire and you may lose the whole litter.

I always used to put the box in half way through the gestation period. Some does will make a nest right then. Then again, a few will make their nest and then dismantle it, only to re-make it at the last minute!

One other scenario would be a false pregnancy. I've seen this a couple of times. The doe has been mated, but it "didn't take." Then, at exactly the halfway point for normal gestation, she'll make a nest. But of course, she doesn't produce any kits. It's a good idea to try mating the doe at this point. If she's really pregnant she'll make a real stink about it! (Remember, always take the doe to the buck, and never leave a doe unattended with the buck.) If she's not really pregnant, she'll probably accept him.
