Rabbit's first pregnancy was unnoticed

About a month ago our Doe, Gabbie, had 12 baby bunnies! I was so sad when I found all 12 lying dead outside of the mother's cage! We had no nest box ready for Gabbie to successfully birth her babies. So I guess the Mother rabbit pushed all 12 babies out of the wire cage?

My daughter had (unknowing to me) let the Doe and Buck "play" together while she cleaned their cages one day. I didn't let my daughter or any of our kids know that Gabbie ever had 12 babies.

Now that I have read what to do to have a nest box ready, we are ready for the birth of the bunnies this time!

Will the mother rabbit know what to do with the nest box this time? As I looked back on the days prior to birth last time, Gabbie had a LOT of fur she pulled out 1 or 2 days before the bunnies were born. And my daughter had told me the day before, that Gabbie was very mean and nearly bit her when she went to feed her!

Day 28 is on April 13th and day 31 on April 16. If anyone can give some tips on what we can do to have some live baby bunnies this time, please post some comments.

Thank you,
