Hi- can someone please help?! I often get minnows from the creek to feed my male khaki and mallard. After eating a minnow, my mallard has been making strange sounds- almost like a little cough. It started yesterday. Even though both are drakes, they are still pretty verbal with one another-quacking up a storm. The mallard seems ok otherwise, and still quacks. Its just that hoarse sound now and again. Could the minnow have been too big for him and damaged his throat?! Or perhaps he is sick?!
