I am going to go look at a couple of Dairy calves tomorrow. My goal is to have a couple of milkers for personal use and excess for other animals. My understanding is it is better to buy babies so they are more trustworthy as adults. I have also read this is a horrible time of year for babies due to diseases. My son looked at the calves today and said a couple of them (They had 50 or more) were coughing. Is this like Parvo in dogs? Kennel Cough? contagious? are the other calves OK? What age is best they have 2 weeks up to 8 week...of course the price goes up with age... Ideas? Suggestions?
