I bought a cute little miami corn on saturday, I also have two ball pythons so I have about 200 mice in my freezer. When the mice are frozen, the legs sometimes brake off. Could the broken off mouse legs be fed to my baby corn?

In the wild, corn snakes also eat birds, lizards, frogs, and sometimes even beetles, would a captive bred corn snake know to eat a bird if one was offered? Is it better to only feed rodents or have variety?
