What do all you Ostrich owners use to carry your ostrich in. Can you add photos so I can see how you pack him?
If you are traveling by minivan you can keep his belly inflated and use a large trash can with wheels to carry him and another character. I don't have an ostrich (yet) so I am just guessing, but that is what I use for my bear and I love it. Of course, with the bear the trash can becomes part of the set as well.
