Triple hutch and babies

[Millimanm]

This is our current hutch. It's shingled and wrapped in fire/water. Tonight it's going to be 32 out, I have almost 2 week old babies too, I'm wondering if I should wrap it with a tarp for warmth? Don't want my babes getting chilled

If the little ones still have a nest box, they should be fine. If they are starting to climb out of the box, you could cover the front with a tarp or something to block the wind if you like, but I think they will be fine.

I do have a question, though. What does wrapped in "fire/water" mean?
