Doe getting nest ready early

[TwoAcreDream]

I have a mixed doe, who was bred November 13 who is now bouncing around with hay in her mouth and in and out of the nest box. I have her in a big plastic dog crate in the garage. There is sawdust and nice fluffy hay in her nest box. I am pretty sure this is her first litter. So as near as I can figure today would be day 23 if I count the day of breeding as day 1.
So I did a quick search to see what the possible length of gestation could range. I came up with this.

Range is from 26 days up to 37 days with 31 and 32 days being the average.

Quite a few of my does would nest up to a week before their due dates. And there are those that nest a few days before, those who nest right before, and those that don't nest at all.
