We have ducklings. I have been VERY careful with not having them in deep water. The one duck however got underneath the running water while I was washing them all off. He threw up twice after I took him out of the water and held him. He threw up the water and food in his belly. It has been 4 hours and it is still opening and shutting his mouth...and panting hard, but not eating and drinking at all. He bobs his head and opens and shuts his mouth. I am devastated as I have been so careful with the amount of water that I put in for them to wash up a little. Is there anything that anyone can suggest to help him? I believe he is about 3.5 weeks old.
