Yes it is cold. But, no bugs or mud to deal with. Knock on wood --- can't remember the last time we had a sick calf. Have lost some ears (and 1 tail!!!) All the calves have a 3-sided shed to get in out of the wind. Big area around the shed where cows are fenced out. All the calves are born inside - well, unless there is a "screw up". Close up cattle are kept right outside the house windows. Anything that "looks" close or is late, gets put in a pen at night. If they calve, they get to stay inside for 24-48 hours. Depending on how the calf is doing, weather and if I am desperate for an empty pen!!! If they don't calve, they go back outside for the day. I can put 10 - 12 in pretty comfortably at a time. Barns are as cold as the outdoors, but no wind to deal with.
