Last night I noticed one of my baby ducklings just laying around. When I picked it up, it was wet and shaking. I guess he got wet from his water dish and I didn't realize that he was wet. I took him out and dried him off and wrapped him up in a towel to try to warm him up. Eventually he dried and stopped shaking, so I put him in another container separated from the other baby ducks because I didn't want the other ducks to step all over him. He/she is eating and drinking water but doesn't seem to have the energy to stand up. When I pick it up, it can move its legs but doesn't stand up. What could be wrong? I read that when they get waterlogged that sometimes it makes them not be able to move, if that's the case, how long will it take for it to get better or is there something else wrong with it?
