f/t pinky on babies kenyan

[Spat]

Hi!
My female gave me 14 beautiful babies last week!
The problem (big surprise ) is for feed them!
Do you think that it's possible to start them on frozen pinky, or it's just impossible and I should start them on live pinky and then, switch them on frozen??
I know that I don't try many times because they just born last week, but my temperature at days is correct, I feed them a f/t pinky in small container with beta chips.
I try chiken broth...no sucess
I think to put them in a very small container at night (near a heat pad because I heat them only with a light, but the temperature in my reptiles room don't drop to much) with a frozen pinky with the nose scratch.
It's my first time to breeding kenyan...thank you for help me!
bye
