I bought a angus cow at sale, most tame cow ever; I believe she is close to calving but don't know for sure, she's not really bagged much, but very loose vulva, she is aprox 6-7 years old, not overly heavy other than she looks like she swallowed a 55 gal drum, heavy with calf or calves? Should her stool be really loose? I have had her aprox 3 months. She eats good and drinks, slow walking though. :shock:
