HELP, please. Concrete floor with topsoil as litter? No roof on end of coop ok??

[rosemarythyme]

I put in a bunch of leaves and pine straw from my yard for the bottom layer and we bought 10 bags of large pine shavings and we only fluffed out 3 and it was enough to cover everything but the open end ...because I'm not sure if I wanna put Shavings down on the open end where the wind and rain can get to it... what are your suggestions for the open end?

I'd actually wait on adding more stuff right now, and wait for some rain or a storm, and see how the flooring and litter looks. Wouldn't want to bust open 10 bags of shavings and then realize it's not optimal for the set up, or that it needs more of other components mixed in, for example. Shavings tend to hold on to a lot of moisture, so not my favorite litter material - but as my climate is way different than yours I can't say it won't work for you.
