Im in south dakota and its below zero right now. I was just wonder when everyone thinks it is too cold to wash or when it will maybe hurt the calves. I have a warm place to wash and will dry them very good when i do wash.
As long as there is water coming out of the hose we rinse. You might need a bullet heater behind them to help dry them in a timely manner which is a must when it is very cold.
We wash when its below freezing still, we hook up the hose to a sink and turn on the hot water in the barn, its a pain, but it gets the job done good luck!!
I wouldn't do anything they calves arn't used too. But they should be alright if you dry them good. Sometimes the calves will sweat so you reallly got to dry good...It takes a little more time.
