any substrate for a run???

[vader]

I am new to this and I am in the process of building my coop.
Coop is 4x8 with 8 ft ceiling
Run is 6x8 with 10 ft ceiling
Should I use any base layer in the run or just leave the dirt and grass. I'm leaning towards pine shavings in the coop. Also how high should the roost be.

Can someone also exam. The poop boards layout.

Thanks

For my runs, I've just left them as they were (dirt and grass). The chickens eat away the grass quickly, leaving just dirt. I like letting them have natural ground, instead of bedding, as they like dust bathing in the soil.

Pine shavings make good coop bedding. Some people use sand or chopped straw, and these beddings can work as well.

My roosts vary in height. Generally, I put them about two feet off the ground. Chickens seem to enjoy higher roosts, but some heavier breeds aren't as good at flying and need shorter roosts.
