I just had a litter of two white chins from a first-time mommy. I don't know what's going on, but today is day 3 and she has been playing keep away from her babies all morning. She doesn't want them by her, and when they try to go to her she will bark and nip at them. But then she will run them down and pin them down before running to the opposite side of the cage. She hasn't drawn blood, but I find it weird how aggressively she's trying to keep them away from her. I put a small jar for the babies in the cage, and now one of the babies (the one she seemed a little more aggressive to) hasn't really left it. Should I give her some more time or start hand feeding or something else?
