My alpine doe is 148 days into her pregnancy. Yesterday she lay down in her stall and has refused to get up. She also has a small amount of white discharge around her vulva and continually pushes her head against the wall of her stall. She has bagged up a little. Her ligaments have sunken but are still tight. Her appetite is down (but not gone). The babies have moved down a little but I can still feel them. When should I expect kids? Thanks in advance!
