I didn't read this whole thread but I did read page 21 where you discussed your Wee Foal results. Just wanted you to know that I, too, had false negatives last year with the Wee Foal 38, and then got positives with ultrasound or Wee Foal 120 later on. Our 3 mares are all due mid-March to April so I will be starting a thread on here very soon. Our cam is up (Mare Stare) but it has to be moved to the foaling stall! Like you, I am hoping the mares cooperate and don't foal all at the same time! Right now the stall the cam is on is empty most of the time.
I wonder if it was a bad batch of WeeFoal tests because we were probably testing our mares at about the same time. Good luck with your foaling!
