That looks awfully light and flimsy -- more of an over-sized budgerigar cage than anything meant for livestock.
It would have to be very well staked down lest a dog or coyote simply flip it over and I'd suspect that any strong predator like a dog or a raccoon could pop the connections between sections without thinking twice. Follow the link and look at the picture enlarged -- the sections just hook like a birdcage and a child can undo that.
It would also need to be completely wrapped in half-inch hardware cloth for security.
Remember that rule of thumb about how anything measured in inches instead of feet is too small?
It's 24 square feet -- enough run for 2 chickens in theory, but feeder and waterer would eat up some of that and it wouldn't offer much scope for clutter and enrichment.
