Is it possible that a mare will foal with no signs of foaling? I have read that she will sink in on the sides, belly drop closer to the ground, wax up teats, ect........... but if mares don't follow the rules, is it possible that all those signs can happen really fast? and you go to bed seeing none of the signs and get up in the morning to a foal?
On the farm where I grew up, my grandfather had always worked horses. We always had a team of drafts. He claimed from his younger years that you couldn't raise a foal there, because they always died. ( I did raise one welsh pony foal there though).
Anyhow, all his talk of how risky foaling is, and them always dying, and "IF your lucky You MIGHT save the mare" has me scared and expecting the worse. When the welsh foal was born, I had a monitor system from the barn to my bedroom. One night it was really windy and the barn was rattling, so I turned it off, and the foal was on his feet when I went to the barn in the morning. I really hope it is that easy this time.
Something else Granddad always said was that if you wanted to rebreed a mare, ( which I don't right now) if you didn't breed her on her foal heat, you would probably never get her in foal again. Is that true? I might want to breed her someday, I don't know.
