Can I ask a question here?? How long have you had Molly? Is there any possibility she was in kid when you got her - that could explain the making of udders. But surely the vet would have thought of this? Never seen any of my goats make a nest as such, although they do paw the ground just before kidding. I think i mentioned somewhere that Harriet thought she had kidded, and kept making bleating noises into the corner, as thought she could "see" something. And then outside, she would run up to buckets, and cats etc. as though she was thinking they were her missing kid!! She went ok again after a few days.
