My suspicions were absolutely correct about Myrtle. Her ligaments were completely gone last night. She is in labor now. Praying for a good outcome today!
Myrtle had a single kid. I haven't been able to get close enough to determine buckling/doeling. Myrtle is a great Mom. Baby was dried, up and nursing quickly. All is well!
Based on the brief glance I got, I think it might be a buckling. Now I have to think of a name!
