Calves?

Yes, we're expecting again ... We're on a list to purchase 2 Jersey bull calves from a farm around here as soon as they are born. I'm a little trepiditious about this whole experience, even though I grew up on a dairy farm. I'm terrified, actually, of losing one right off the bat. I watch our critters for signs of illness all the time. We'll have to bottle feed these calves colustrum for the first few days and then bottle feed them milk replacer after that. I know that all the calves born to my grandpa's farm were bottle and then pail fed milk replacer. He did not leave calves with their mommas at all. A few of them didn't make it including my beloved Albert. I'm also afraid of my husband becoming too attached to these bundles of beef. I'm just going to have to remind him that they are cute now, but they will be tasty later. Any advice on what I should do to keep them healthy the first few weeks? I do work full time so I can't stick around the farm every day, but I will be stepping up the doing of the chores, especially now that it's warming up - over 40 degrees F today!! In Michigan!!!!
