I have two Nubians due 14th and 18th. The one due the 14th went from having rock hard ligs the last 2 weeks and all day of checking and all of a sudden to very sunken almost not feelable tonight . I put her in the kidding stall with the other doe. How likely do nubians go on day 146. She needed assistance as ff year and half ago with twins so I'm worried I'll miss it and shell need help. Do I stay up? Checks thru the night? I can run out and get pics if that helps. Have pics posted in waiting from yesterday. Thanks!
