How long till she foals?
It sounds like it won’t be very long at all, like less than 24 hours. When my mare foaled, she had those same signs and the muscles of her rump appeared to be very soft and squishy, even though previously they were firm and toned. Be prepared. Most mares seem to like to foal in the early, early hours of the morning. By this time tomorrow, you could have a new baby. Good luck!
