I can clearly see the leg issue in The video she should not be swimming right now. She should be giving them vitamin b treatment and the therapy treatment.
Understand when baby ducks are with there mommy the mommy puts them under her wing. She does this to put her oil on the babies to protect them from drowning, it keeps them a float if you look or watch any adult ducks you will see the water rolling off of them that ther oils, we can not duplicate this so therefore Baby ducks that have been hatched have not developed there oils yet. So ther fur is like a sponge once they hit that water and it weighs them down.,, so I would strongly suggest no baths or swimming. At least until they are a week old but in her case until she can hold herself up..
