Okay, this isn't specifically chicken related but I know many people have other birds, so maybe someone can help with this question. I have a couple of adult geese and a duck that I am selling to someone who's about 400 miles away. She suggested possibly coming by air and taking them home that way vs. driving up and back. I am wondering if the air travel isn't harder on the birds than a longish car trip (5 hours, I'd guess). Any thoughts on this would be appreciated as I have no experience transporting adult birds. Thanks!
