Quails aren't eating whay should I do?

I've got 3 hatched quails and it's been about 20hrs I cannot get them to eat or drink, I've tried putting them when the mother but she doesn't seem to keen on them and just ignores them and she even went to peck one but stopped her before she could and got them away from her.

I'm worried about them cause they look hungry and keep vocalizing louder when ever we move away
