Type of sand in run

[MiloDaisyMissy]

Hi All, I have my coop and have decided sand is the best way for my guys in order of keeping it clean. I can't find sand course enough here. I'm in WA Western Australia. These below are my options that I can find so far... Which one would you pick? They all seem too fine or too coarse? Thank you!

Is crushed limestone an option even?

I’d probably pick the gingin quartz sand, but it’s hard to tell the actual size of the particles in the picture
