Baby chicks are OK to feed. But the problem is, will your snake actually take it?
I know my snakes won't. But there are people out there who do feed chicks to their BPs.
But be aware that chicks make snake poo really runny. And chicks/birds do not have a dense skeletal system. Their bones are hollow, so your snake might not get enough calcium if you make it a staple diet.
Don't offer gerbils or hamsters. You'll never get your ball Python to eat anything else after that. Its not worth getting your snakes stuck on expensive prey.
