Yup, I've had loads escape. Can't you just chuck the chihuahua into a different room? Then if they DO escape while your not present, its in an enclosed room with no predators.
I would do this instead of putting them on an unprotected porch where their only defense will be the cardboard from the box that they are in. Cats would be your main issue,they stick their paws in & try to snatch chicks.
