Answer 1

IF YOU ARE USING AN INCUBATOR,CHECK THE TEMP,THERMOMETER SHOULD BE SET 2/3 OF THE EGG HEIGHT,CHECK HUMIDITY.

Answer 2

I wouldn't give up just yet! My friend had ducks and sometimes they don't hatch for up to 5 days late! I would also try candling the eggs to make sure they are fertile. I included a How-to in my sources! Hope this helps!
