so I have some ducklings that are about 4 weeks old they have all been fine but then 2 days ago they were outside swimming in the kiddie pool I have set up for them and I went to move them back inside. They usually run away from when I go near them but the one didn't move. She just sat in the pool and was shivering. I thought she was just cold so I moved her inside and set up the heat lamp and tried to dry her off. Like I said they usually run but she let me hold her and didn't really fight other than making some quacks and shivering. So I separated her bc I wasn't sure what was going on with her. She has been eating and drinking ok still. Her poop is still normal isn't super watery or different colored. It's been 2 days. She stopped shivering but her breathing seems a little off. Trying to figure out if she's actually sick or if I am just freaking out over nothing.
