Help! One of our does that we thought was due with the rest (last week) hasn't kidded. She is a two-year-old, first breeding. She is definately pregnant, big saddlebags, kids moving (at least two!), udder development...if she missed a heat cycle, she would be due in two weeks. QUESTION: in the last couple of days she has developed a stiff gait...not just a preggo waddle, but stiff gait, and popping, cracking joints. Any ideas? Anybody see this before? What to do???
