Anyone else opting for the poop-fall-through method?

I am wanting to change over to galvanized sheet metal poop boards when the weather warms up. Easier to scrape

and get all of it. I use a stainless steel 8" drywall finishing knife and it works great and does not stick

or get rusty.

Have you had more experience? Does it work better than laminate floor roll glued over osb? What about aluminum? I thought metals react with chicken poop over time, even if it doesn't normally rust in just water.
