I have a basket with a lid which is comfortable for one adult goose, but often used it for the two goslings I reared by hand. I'd take them with me if I went away for more than a couple of days, and they would ride in the basket on the front passenger seat, watching out the window and would do so for hours at a time. Reactions from other people when they realised they were being watched by two geese were priceless...They seem to prefer riding like that rather than being in the crate.
