Ok she has a nest box and moves the straw around. Her personality is definitely different, she growls now. I didn't palpate her but she whimpers/grunts if i touch her belly. I don't want to palpate her because she makes so much noise if i touch her belly. She hasn't pulled any hair though. Oh and she is a large breed. We believe she's Flemish Giant but she is probably just a mutt.
Gestation is anywhere from 28-32 days with an average of 30. So my guess is she isn't going to have any kits. Not that unusual if this was to be her first litter. Best bet is to try again. Be patient. And good luck.
