Feeding Chicks?

Just had a question regarding feeding snakes (specifically Ball pythons and Boas) Chicks every once in a while? my mom breeds chickens and offered to give me ones with no quality of life (not sick but deformed feet, crops, beaks Ect.) Is it safe to feed my snakes a verity of foods? all of them are over 2 years old and up to 7 years old.
