I am so relieved to hear that your mare came though this unharmed. I am so sorry for your loss of the beautiful filly. My mare that was carrying twins had two colts that were described to me as beautiful chestnuts with blazes and four high stockings. I never saw them, but did mourn them. But keeping my mare safe was my only concern, just as it was yours. Bless you for being so observant and so conscientious. Hug your beautiful mare for me.
Awww....you did the right thing and got the right advice. I'm so glad to hear your mare will be fine. That was a terrifying situation. Something was just wrong, and you saved your mare. Good luck with her in the future and may your broken hearts heal.
