I have a runner duckling that is about two weeks old, and today as I was sitting and watching her drink I noticed that instead of taking a few drinks and then going back to do whatever ducks do when they're not eating/drinking, she didn't leave the water bowl. She sat there for a good five minutes just drinking and drinking and drinking. I've never seen this before so I scolded her and when she stood up to walk away all kinds of water poured up and out of her mouth and nose. I freaked out a little, I'm not going to lie. And then she sat back down and started drinking again. She stood up, threw the water up. I could hear her gurgling past it. I ran a tub for her and I placed her in the water so she could rinse off or dunk her head or something, which she did, but she also kept drinking. I placed my hand in there so she could sit down and rest and she wouldn't drink, but she'd still lift her head and make little drinking noises like she were drinking. When I placed her back in her pen she vomited the water back up again. What's wrong with my duck?
