My 2 year old (almost 3) looks to be about to have her first calf. I bought her bred and they did not know when she was due. Anyway yesterday she had some stringy blood on the tail. She has benn sticking close to the run in shed and my older cow has been "babysitting" her. We have checked her every 4 hours last night and every 2 today. My major question is, do I need to blanket the calf? I live in Vermont. Lots of snow and about 25* daytime temp. I do not have a barn for her. Not to mention I think she would freak about leaving the herd. Any advise?
