Do you have any soft food in the cage for the little ones? They probably can eat a little bit on their own but might not be able to crack shells open yet. The pet stores sell dried egg biscuit. You can add some water to make a mush. You can also offer hard boiled egg that has been mashed. I used to make a soft food out of jars of pureed baby food. I'd mix carrots, egg, spinach, and rice cereal. This can be frozen in ice cube trays and thawed as needed. It can also be offered as a treat when the birds are grown. Dad should be able to handle it by himself if he's been helping out all along.
