How long does it take for a zebra finch egg to completly hatch after it starts cracking?

Question

Its hard to explain but not when the egg is first laid I mean when they begin to crack how long does it take for them to get out?

Answer 1

This is hard to answer since we are not the baby bird trying to get out i would say this depends on the baby inside if its strong enough to peck long enough and not tire out for how long it takes If one is ill may take longer or may be shorter  best just watch and see how long it takes for yours.
