I do that because the bricks are free and anything that doesn't have to be permanently installed is a win for me, because I'm not inclined to actually build things. The bricks don't all have to be at the ends, I have some in the middle too now.
I think I remember your coop build now... you had...
Oh I should've expanded the photos (I didn't realize the roof was right there, I assumed the coop was far taller). I agree, more frequent cleanouts are probably the best way to manage things as you don't have room for deep litter, deep bedding, nor poop boards.
Poop boards need enough...
x2 - your coop appears elevated. Deep litter works best on a dirt floor because you want moisture and microbes to break down the poop. Moisture is something you otherwise don't want inside a coop.
I assume what you're actually doing is deep bedding which is a different thing, dry vs wet...
