That was convincing! No mesh. But still more into the raised style to make use of the ground under..
Is this because you have limited space? If you have to go with a raised coop, make sure it is high enough to easily clean, and make one side able to be opened almost entirely for cleaning. Then get children's hoes and rakes for cleaning. The poop boards wont work, so you'll have to do what I do. I just clean the coops every day, taking all soiled straw or shavings out and replacing it. Because I didn't start with a walk in coop and enclosed run, my work is a lot more than it would have needed to be.
I started with 6 chickens, thinking that's all I ever needed. Then I learned about chicken laying habits, and realized I needed to add a few every year to keep eggs coming. Planning ahead, I started adding 3 chicks per year. Next thing I knew, my 10x4 raised coop was not large enough, so we built another 4x4, and that worked for another year. Year 3 began with yet another coop to accommodate the 3 new chicks and keep them separated in a see/no touch pen for a couple months. Now I had 3 coops, all being used. All hutches. Year 4 inadvertantly brought two cockerels into the mix, both of whom I fell i love with , so I'm trying now to figure out how to keep them. DH built coop #4. Now I have Coop #1, (10x4), Coop #2, (4x4), Coop #3 (prefab 3x3, because I didn't have the heart to ask DH, and now it's falling apart), Coop #4, (4x4, built by DH), and in March, at the beginning of year #5 we are building coop #5. I currently clean all 4 coops every day because it's winter and they spend a lot of time in there doing what chickens do!
Coop #5 will be an 8x10 walk in coop with all those spaces above and below
inside the coop. We will be able to divide it into two coops and runs as needed, and have a space for brooding mamas. I will keep the other 3 DH built coops for isolation pens when needed, but will not use them. Next winter I'll be headed out for the 5 minute scoop the poop off the poop boards, have large water proof feeders and heated water dishes under a full roofed chicken run (min 120 SF) and will not be dealing with this winter mess anymore!!!

They will still be able to free range in my orchard every day, which is surrounded by electric wire, fencing and covered with bird netting. I can't wait!
I still only have 12 chickens. That is the approximate number I will always want, but it will ebb and flow with chicken life cycles.
I'm just sayin...
