Feeding Coastal Python

[ken99]

I have recently bought a Coastal Python. He is only a baby at 14" in length.
I have had him for 3 weeks but have been unable to get him to eat. I have tried baby mice (alive and Dead). The dead ones were thawed and warmed first but he did not seem interested. His tank is thermostatically heated and he is very active and likes to be handled.
Should i be concerned or should i persist and just wait.
