Mares dont have the same gestation every foaling. We have one mare who foals within a week either side of 310 everytime but we also have one who is all over the place in terms of number of days gestation you just never know. There have been successful foalings on this forum all the way from 278 days to 360 days so just hang in it is very nerve wracking for all those who do mare stare thats why my Scoopie is in charge of that end of things here it drives me crazy. She has pages and pages of notes on each of our mares and literally spends nights watching when she gets little or no sleep. This year we only have one mare bred so Jodi is watching the mare stare cams of others. Go figure. Good luck with your mare cant wait for a post that you have a healthy baby and that mom is doing fine.
