I'm planning on attending a show later this fall and will be bringing a considerable number of birds (more than can fit in my vehicle). So I am looking for any suggestions on what to use to haul the birds. Its a 14 hr drive I might add. I am considering renting a pull type U-Haul, but worry about air circulation and temperature inside. (show is in October). Other than that I have considered seeing if anyone I know would let me borrow their horse trailer, but the majority are either too large or too heavy. So have any of you used U-Hauls before? How'd it work out? Any tips? Thanks!
