Well, they didn't stay small and fluffy for long.
Soon the geese were feathered enough to go outside.
No problem. That spare dog crate in the garage worked just fine. And because the garage floor tends to be a little slippery a nice rug was set down so the geese could enter and exit their bed without any slip and falls.
The poop? Just had to give that rug a good shake, a little soap and water then dry it in the sun. All garage rugs should look so good.
