Very Awesome!! When I read the title I expected to see a picture of a card board box with something over the top...but lo and behold see this!! GREAT JOB!
Quail poop and possibly spilled water, I would imagine..
I'm in the process of building my second button cage, but I use wood for it. We get the wood for free from a local store - basically everything that gets damaged or things they have used for displaying products, pallets that don't have standard measurements - everything they can't sell. Only problem is we can't use it as fast as they throw it out, we can hardly get around on the property, wood everywhere ^^
