I have a chimaine heifer bred to an irish whiskey son and this is her first calf. She was AIed at 2 years old on March the 26. I had someone to come and palpate her sometime in June and she was confirmed bred. I had a limousin heifer bred the same week as her and she calved her heifer calf on January 1. On January 3 I had the same person come and get her checked again but he told me he couldn't feel a calf. However, he did tell me that her mammary veins were starting to fill up. As of today she is 15 days over due and I'm starting to worry that she has either aborted the calf or she had a miscarriage. I have been keeping an eye on her every day since December 21 and not one of those days did I see any signs of heat. She has been having some clear discharge for a couple of weeks and she had a yellow looking mucus discharging from her vulva January 2. She has been on nothing but hay and very little feed but she looks very deep and wide for a heifer who has been on mostly hay. Looking at her udders I would say she isn't bagged up but they feel like there is milk in them and her vulva is swollen but to me it doesn't look loose enough for her to calve. Has anyone had a heifer go that long?
