So here is Wednesday's am update.
Jewels had full hard bags for the first time last night, so I do believe she is finally ready to pop, and I have for the first time alerted my veterinarian to a birth.
Meanwhile, Susie, who is a week further along than Jewels, started getting bags last night and has a history of bagging up and foaling within a few hours. She has been restless and yawning all through the night.
Susie ONLY LAYS FLAT WHEN SHE IS FOALING. So if you see her going down in a meaningful way you are likely about to see her foal.
I have a monitor to watch them next to my computer and I am watching them inside for another hour and then will head outside to check them when it is light. I will swich to just their cam if I have time before they foal.
