I have a baby mallard who is about 9 days old. He is seems to breathe very short and quick and he usually has to open his mouth in order to breath, he is a lot less active then he used to be and seems kind of sick. He doesn't chrip much at all anymore and I do not know if this is because he is getting used to me or is not well. He also does not seem to be going to the bathroom as often as he used too, I have already cleaned his feathers around his bottom to make sure that nothing is blocking it on the outside. This has been going on for 2 days and I cannot tell if he is getting any better or not. ( The only reason I even have him inside with me is because all of the other babies, that were hatched out by the hen, were freezing and dying outside because it was too cold.) Any suggestions on what to do if he is sick?
