We have a three week old holstein bull calf in an outdoor 8x8 calf hutch (we are in Southern Illinois) and it is feeding fine, drinking water, no runny stools, but has a runny nose and wants to sleep all the time. We know the calf is ill, but are not sure what it is. Breathing seemed fine last night when I looked at him, but this morning when I checked, he seemed to be laboring just a bit in his breathing. Is it pneumonia or something else? We have raised feeders up until now, but I do remember growing up that when you see a young calf ill, you must act soon. Your thoughts and opinions are appreciated!
