my geese are sitting on 5 eggs and i havent got a chance to candle yet, but im sure that some wont be fertile, everytime ive incubated geese eggs ive had to help them in some way during hatching, and i dont know if these will need help, or if the parents can handle them, i dont want them to die.... will the eggs hatch sucsessfully under them or should i try to intervine?
