[blackbelly] Possible Sick Pregnant Ewe

[JKTBAND]

I have 3 ewes and 1 ram.  1 ewe delivered a still born about two weeks ago (looked mostly developed, but no hair).  She's since been eating fine and appears okay.  Still not sure what caused this.  1 ewe looks pregnant, but still a while to go.  My problem is with the remaining ewe.  She is twice as round as the other pregnant ewe, so I'm guessing possible twins -1st birth for her.  Up until yesterday things were looking great.  The sheep have constant access to a huge round bail of hay in a covered shed and I've been feeding grain daily (enough for each to have about a pound).  The ewe began bagging up about 10 days ago and looks full now.  Her "rear" is slightly swollen during the last few days and the side of her hips sunken a bit -basically some of the signs of a nearing delivery.  Unfortunately, I noticed yesterday that she began looking a little depressed (not laying a! round or stumbling, but just slower than usual).  Today, very oddly, she would not eat the grain (she usually goes right for it and digs right in).  Also appears she's had loose stool today.  Should I be worried that there is a problem or could this simply be part of immanent delivery?  I'm checking her every couple of hours, but she still shows no signs of labor (no heaving breathing or straining, or lying down).  Also, in the event that nature takes it's course and everything is fine and I've got new babies in the next day or two, will the babies be okay in the field and stall in the cold weather?  It's supposed to get into the 20's here this week (no precipitation), will the kids be okay or should I catch them and mom and bring inside?  Appreciate any advise.  Thanks -Kyle.
