Be sure he's breathing smoothly. I had a 5 year old Saanan milk goat get pneumonia and there was congestion and snot and later I saw some breathing strangeness. At the very start I thought she was just bloaty (which she was prone to). I got her a shot to cure it and it worked wonders. However you have to work fast. I wasnt fast enough and even though she got better, she went downhill slowly after that and died from something else. Cant say if the pneumonia was the trigger or if it was a side effect, but it can be serious. I'd watch that little guy very closely.
