Nest Boxes

I use two main kinds of nest boxes in my indoor cages (the outdoor cages have built in houses so don't need nest boxes):

Plastic ones made from storage bins with a hole cut in the side:

Wooden ones made using plywood, 1×4“ boards, 2×2”. They measure approximately 18“ deep x 12” wide x 9“ high. I have built a few that are higher (about 12”) for my bigger does. The does love to sit on top, so the lid is important. As I breed year-round, I also think the does help to keep the kits toasty warm when they sit on top. :-)

As you can see by the reading on the thermometer - the nests are toasty warm. That last photo was taken in December when it was -25C (-13F) outside.
