I have to avoid winter calving. I am just back in the cattle business after 30 years away from it, and have bought some that were fall calvers, due to my lack of patience, or maybe my excitement to get the ball rolling. That sounds better. One bred heifer I bought from a southern lady calved 2-4-14, when it was -5 degrees. She was in the barn with bedding, and did fine, but if she had been out in the wind things would probably haven't turned out as well. I will work on getting the calving season to be in the spring, which starts in March here, although it was cold with plenty of snow this year.
I had them preg checked which got a few sold, and a few put in a field away from the bull. He is with the bred cows, and when they calve I get them away from him. He can see them again June 1. He is much happier with cows around him, even though they aren't going to come into heat with babies in their bellies.
