A photo of your snake and the enclosure would help a lot, it may be that your setup is not right. What are your temperatures and humidity? What kind of substrate? It's best to try to feed them late at night before you go to bed since they are nocturnal. Chicken broth? I never heard of that one LOL. Are you using frozen thawed? How do you heat them up? Do you refreeze or toss them out? You should try to get a weight of your snake in grams, they tend to fast around the 1000 gram mark.
