hi everyone

i got hatchling baby butter ball python (hatch date 10 nov 2011, got first shed on 19 of nov 2011)

until now she refuse to eat anything, i try various food item (rat pup,jumper mice,rat baby to pinky mice) and all she do is strike it heavily but refuse to constrict and eat the food item...all her siblings is already eat

i also put hiding inside her cage

her condition is seems 'ok' still full alert, not weak or appear sick.

is this condition common in ball python hatchling ? (this is my first breeding year)
any advise to handle this situation?

thanks for any help and input
