Update-I have been back off and on browsing topics but have waited things out here, and no babies. She has never had blood anywhere or any signs of having given birth at all. So I believe her first breeding was unsuccessful as I had thought. The nest is still there, and I think her second breeding (when I saw him fall off twice) may have worked. After about 10 days or so she became really moody again, tearing up her cage and lunging when we try to feed or pet her. Today is day 20 and the first time she was done building her nest by this point. Now the nest is still there but she's not been Haystaching more or adding to it yet (assuming she would). I put her in with the buck today and she growled and bit him. Last time day 20 she was ready to let him breed her. So all this being said, fingers crossed for babies after Easter!
