Ok, first off, do NOT assist or force feed. It's an absolute last resort for hatchlings that haven't eaten at all.
Second, pinkies and fuzzies are WAY TOO SMALL for a BP. BPs eat hoppers out of the egg for only 3-5 meals before moving up to small adult mice.
Now, in order for us to help we'll need more info. The more you tell us, the better we can help you.
- what type and size enclosure is the snake in?
- how are you heating the enclosure?
- ARE YOUR HEAT SOURCES REGULATED BY A THERMOSTAT?
- what are your temps? How are you measuring temps?
- do you have at least two properly sized, secure hides?
- are you handling the snake at all?
- is the enclosure in a high traffic area of the house?
- how often are you offering food?
Remember, be as thorough as you can so we can help you the best we can.
