My mare foaled 72 hours ago, her and foal are doing well, She is eating normal, stools are normal, no fever. This morning I noticed that she was winking and squirting a milky yellowish mucus (sp), no puss just off yellow. My question is; it's too early for a foaling heat, I believe foal heats are about 10 days, I believe the yellow discharge to be normal, but is the winking normal? We plan to A.I. her during her foaling heat.
