I have a 6 week old Nigerian Dwarf buckling, nursing from his mamma still, who today has started sneezing and whiping his nose on the fence and enclosure and also sounds just a little rattley in his chest. No fever and he is eating fine still. Is this a "wait and see" or a "jump on it now" situation? The books are all vauge and talk mostly about once it turns into pnumonia. I have no newcomers and everyone else is fine. Thank you for any advice you can give.
