I have a large dark brown doe (i have no idea on the breed..) and a harlequin/netherland dwarf buck and i seperated them after they bred and their cages are about 20ft apart. She built a nest and everything but she still hasnt had babies and its been about a week since she made the nest. this morning I saw blood on the nestbox and thought she must have had babies. I felt in the nest and there were none!!! I didn't see a miscarried kit and im really worried... What do you think happened???
