DO not feed Chicks. They do eat them in the wild as do many other snakes we keep. Don't mean we need to feed it in captivity. When feeding HIGH protein meals like chicks their feces are very very foul and will fill the room with that smell.
I have a 15 year old cali king i got when he was 2 months old and only ever been fed mice his whole life. Rodents are plenty for them to thrive off of.
