Alternative Duck/goose house

[aaronburton87]

Hello, I will be raising 7 cayugas, 3 golden hybrids, and two buff geese.
Rather than a traditional barn, I would like to use a garage in a box (refer to photo).
The one I would like to use is 150 square feet, will this meet the requirements for them to live comfortably (If I'm going to eat their children, I should atleast let them feel at home)?
Safety isn't a concern, I'll be putting up an electric fence.
I have 7 weeks before I need to worry (ducklings and goslings don't arrive until June 7th, already have a seperate brooder setup), but I like to plan ahead.

I can't see the image, but I googled images for "garage in a box".

My main concern is ventilation. On a sunny day they'll steam in a garage like that.

Also, geese like to gnaw and pull at stuff, and given enough time they could rip the cover to shreds.

Fully feathered geese and ducks don't really need shelter except in extreme conditions. Such conditions would very likely wreck the garage anyway, so if they're already protected from predators, why bother with housing at all?

I would like them to be out of the indoor brooder by 4 weeks. You can roll up the front side of the shed and get proper circulation with a fan. Utah wi ters are my main reason for seeking shelter

Don't waste your money. You will have to go back and add hardware cloth or chainlink underneath to make it somewhat predator proof. They also aren't the greatest in the wind. My brother had some cars stored at my place under them and they didn't last one winter.
My goslings were out 24/7 at 5 weeks happy to sleep under the stars in a dog pen. Most people around here keep them in large kennels (10x10) tucked under a loafing shed with a dog house for bad weather.
