I have a first-time mom trying to build nests on the wire in the 2 rear corners of her cage. She started this behavior before it was time to put in the nest box, so I gave her a shallow cardboard box which she shredded to smithereens overnight, and then continued to try making nests in the back 2 corners on the wire. So I gave her the nest box lined with cardboard (this is a brand new nest box) but otherwise empty. She eventually got the cardboard out and tore it up. No nest in the box. So yesterday (the day of the photo) was the actual day I was to give the prepared nest box, so I filled it with hay. Next thing she does is grab a bundle in her mouth and starts building in the corners on the wire again. I'm a new rabbit keeper and she's a first-time mom, so together neither of us are sure what to do.
