It can be a sign of dehydration and shock. Drops of light karo syrup, followed by a few drops of water or better - electrolytes, should help them pick up and go, follow it up with poly-vi-sol without Iron, and if they're meant to survive that generally works.
Instead of Karo you can use sugar water but in some chicks that will cause pasting (poop stuck to butt and feathers). Light Karo is better than Dark Karo, dark Karo contains more molasses which is more like sugar and can cause pasting or diarrhea.
Karo is better digested it requires less work of the digestive system, conserving energy and calories. Electrolytes either unflavored pedialyte or the powdered mix available in feed stores, help more than plain water.
Don't use raw honey - it contains bacteria that can be deadly to infant animals and infant/toddler humans.
