You don’t want them to hatch faster. If they haven’t fully absorbed the yolk or had the blood vessels shrink, hatching faster would be bad for them.Is there anything I can do to help them hatch faster? Like turn off the lights? Make the room quieter?
Having said that, they will hatch a little faster if they can hear the peeping of the ones who have hatched. They do not want to be left behind if mom takes those who have hatched to the water source.
