How does a baby of the bird eat inside the egg? Are there holes for that also?
No, No. There is no such hole. You must have seen a broken egg. It contains two parts-the yellow portion and the white portion. The yellow portion is called the yolk. The baby bird gets its food from the yolk. The white portion is called albumin. It surrounds the baby inside the egg and protects it from the sudden rise or fall in the temperature.
