I just purchased a seven year old Reg. Angus cow She will weigh 1500 lbs heavy with calf looks great. I just noticed her walking funny, she throws her back legs around as she walks not straight forward like the other cows, and her back legs do seem a little straight. She may have been like this all along but she was in mud when I first looked at her and I didn't notice. Has any one had anything like this.
