My beautiful Azteca mare Felina is at day 351 with her first foal. We though she might deliver last night with the horrendous storm that came through and a full moon, but alas, she did not. Her belly dropped yesterday and this morning she is waxing and her flanks are sunken in. We tested her milk yesterday is her calcium is high but show is the pH. This is nothing like kidding season, which by the way, I am in the middle of! I'd love to hear from others about their maiden mare birthing experiences.
