I went outside to check on my animals and I found all 10 ducklings in the water. 3 had already passed so I emptied the pool. Right now 3 are dead, 4 are alive and running around, and 3 are moving but barley. What can I do for the 3 that are on their last leg. I only left for a little while and left someone in charge but they didn't stay out there and watch them. I really need help now.
