Shipping Cornish X Rock and Bantam Chicks, Together?

[Harmony]

Silly question I know, But has anyone ever tried to ship them together? I'm curious how they did, I'd like to order a dozen Cornish X Rocks with some Bantams,.. but I've been told the Bantams somtimes peck at the Cornish X, or the Cornish X will trample the Bantams should a bug decide to fly in the box?

I would'nt think it would be a problem but i am sure someone with more knowledge will chime in..
