What to use over wood floor of goat house?..no, can't remove it

[feathernfiber]

I'm getting my first .goats in 2 weeks. Their house is a star plate geodesic dome mounted on a wooden platform that is raised on one side and level with the ground on the other. The platform, which looked like a deck before I mounted the frame & put on walls, is pressure treated 2 x 8 pine. Its 11 ft diameter. I cant just pu the goats Iin with hay & woodchips because the litter & berries will get stuck in the cracks, build up, & ruin airflow/ drainage underneath.
My options as I see it ( without removing the floor) are sheet rubber mats (pee goes undernearh the overlap, right?
Stall mat interlocking tiles, which I would cut to fit (the pentagon) or ? What? And I will use crushed limestone or sand and soil or both on top of that & clean it out twice a month. It will house. 2 NDG does. Here's the deck before ...oops, I cannot figure out the photo upload from my.mobile. Just picture a dark brown stained pentangular deck in the middle of a pine & maple woods

Plastic sheeting,tacked down and covered. Can be lifted up and changed, home depot has it in rolls. Or for a more long term......vinal...

Rubber mats would work if you used rubber caulk (get at hardware store) to seal the seams. Otherwise, I'd go with kinder's idea. I don't know where you're at but if it gets freezing temps then I wouldn't go with sand. My preference is crushed limestone over soil as it's easier to sweep out after it's compressed.

I'd go with horse stall mats and use Liquid Nails to caulk the cracks. On top of the horse stall mats use wood chips. Then I would shovel it out weekly and get inside the goat hut with a leaf blower and blow out what can't be shoveled. Reapply wood chips after each clean out.
