I have 2 chinchilla does who are going through their first pregnancies. They're sisters, and they share a 'habitat' space rather than individual cages. (We have a sort of controlled colony setup). Alice was due today. We have 4 nesting areas available between the 2 girls, and we packed them with hay in advance. Alice never showed any sign of nesting or fur pulling, so we assumed she'd probably be one that waited until the last possible minute to do so. We woke up this morning to one new baby bunny alone and cold out in the yard, rather than inside of the nesting areas. We looked for more, and when we didn't find any others, we moved him into one of the nest boxes and showed Alice where he was. I pulled some of her fur to keep him warm. She didn't show much interest, so we stepped away to leave her to do her thing. Chloe, Alice's sister, happened to start first thing this morning building her nest. She's due on Saturday. She worked at it all morning, lined it with fur, and it was actually quite impressive (more of a hay burrow than a nest). I stepped out to check in on the baby bunny (it's a cool, rainy morning and he's all alone), and Alice has stolen Chloe's nest and is giving birth to more bunnies! I moved the little male she left in the yard into the nest with her. Has anyone ever had one of their does steal another doe's nest? I'm hoping Chloe will build another for herself before Saturday... Alice just never even tried to build her own, the little thief.
