Sorry I haven t taken time to introduce myself, I've been reading silently from afar. But I have a problem that's new to me and I could use some advise. I have a 6 month old calf that is shivering, head drooping, and hanging back from the others. He does not have pneumonia, his breathing is fine, nose clear, and no hacking. At least he isn't yet. Gave him penicillin and Baytril hoping that will help. Temps are very cold here, ice storm last week, 4 inches of snow last night and the wind is blowing. Tonights low is suppose to dip down to 7 degrees. He is in a loafing shed with good ventilation and a fresh layer of cornstalks. Has anyone any advise?
