first of all, you cant; ducks are confiscated at security checkpoints, so its essential the duck is placed in the luggage section
unload the chamber and disassemble the duck or dont (depends on TSA's duck designations) and place it in a secure container

make sure with the person checking ur luggage if everythings alright and youre done!
