I am having a problem with my ducklings just keeling over for no reason. They are healthy, warm and all that, it happens right after they get water. If their waterer (a chick waterer) runs out for more than 2 seconds and I re fill it I come back to a brooder FULL of dead ducklings. The other day I lost 20. What is happening to them. The water is clean, their environment is fine, all that is in order. It seems that they are gorging themselves on water and then they just fall over. I've checked their mouths and all and don't see any food pasted in their mouths or throats. I have never in 7 years had this happen til this year. I need to know what the heck to do, I'm scared to water them but I know I have to. What kind of set up do they need that will prevent this.
