It really depends on the chick. Some have pooped in their shell before finishing hatch.I know this an old thread, but I have a question. How long after a chick hatches, will it poop?
But I think all should be putting out some poo the end of the first day if their digestive system is working correctly since the yolk is the first thing they digest and pass even before starting to eat.
I never imagined I would celebrate poo.

Hope all is well!
