Okay, as you know, i just got my first nigerians. However, after driving (with their former owner) on back of a truck in a crate that didn't have much windbreak, for 3 hours, it seems they have a slight cold---- which includes coughing, (daisy had a runny nose yesterday, but gone now), a runny eye, and congestion. The horse trailer had alot of windbreak so I know it isn't from the drive home. They are alert, vocal, but I just checked them and it appeared to me that their noses were a slight bit warm. I kept them away from my other goats just in case. Is this is just a cold? any homemade treatment methods? or could it be, that this is something worse?
