Hello! I got 2 cayuga ducklings 2 weeks ago, they were 2 days old and are now 3 weeks. They keep making this noise that sort of sounds like theres something in their nostrils and one of them has been sneezing, it hasn't sneezed since I let them in the bath, but still making the noises, one sort of sounds like its honking as well, does anyone know if this is normal? I've looked in the nostrils of both and cant see anything
