You're in good company! Last year, the 2nd calf born was 4 weeks earlier than anticipated, but still huge. Mama is our oldest cow and even though it was -20 wind chill, she's a pro and had that calf up & nursing in no time. Took a glance, bigazz bull calf, all good. Decided to name it Bart, after a local radio station mascot (Bart the Radio Bovine). Bull calves get tagged in the right ear and I tagged, First Defense, Inforce 3 no problem, calf was good to go. Except a few days later . . . . ummm, where's his junk? Okay, so, what I initially saw was a big, furry navel. And I'll be damned if I was taking off my gloves in that cold just to cop a feel. My bad! But she's butt ugly and a big, strappin' farm girl, so she kept the name Bart. And the rest of the story? Yup, I kept Bart as a replacement because her lineage is one of my most prolific. Her pelvic measurements were HUGE and, just based on observation, looks like she got bred by Tallywacker right off the bat when I turned him out in May.
