This forum has thousands of pictures of cages and asking people to post them again for you is the best way to not see any of them. Use the search bar and youll be able to find more quail cages than you have time to look at.
It was a rabbit hutch I found on craigslist for cheap. I added the boxes and later some branches so they could get off the wire on the bottom. They never use the branches but sit in the boxes a lot. Sometimes they lay in there and other times I find eggs on the wire. I fill the box with sand or pine bedding. I have a bunch of both leftover from my chickens. Do you have a quail set up?
