Well after a busy day at the gym and doing a massage, feeding, general chores and selling a couple of hens, I discovered my broodmare had waxed up at 530pm so I spent 3 hours moving ponies around, dragging and fitting/fixing/kicking/untangling hoses and walking back and forward to see whether water was running to the furthest field yet.. Got the barn ready just in case of need, more water to fill by hand with buckets, bedding etc, and settled in for an interrupted night.
At the 1130 check it was blowing a hard north wind and started to snow while I was up the field so duly dragged the mare into the barn pen and the stallion and other mare just outside. Mare wanted to wander off back to grass, stallion frantic herding her back so in the end I put the two into a pen beside a barn and filled more water buckets for them. Tried to sleep but was back out at 140, 330, 440, no sign of a foal tho so have it all to look forward to again tonight. Tho I expect she'll foal in daylight up the field and I'll have to fetch in all 4 by devious means to protect the foal and not upset the others.
Got to be out a few hours today so that is my best bet for her timing it, about half an hour after the car drives off..
