I didn't ask a question,
@Oreoandhens did.
But I'll tell you why I do it my way.
My coops are about 3.5 feet wide, about 3.5 feet high where the roosts are. No room for poop boards.
My coops are raised with wood floors, one resin coated, the other painted. No deep litter gonna happen here. Shown here during rebuild before roosts and 4th wall added.

Like I said egg sales pay for everything my hens need to be happy, feed, scratch, and shavings.
All 3 are sustainable, just plant more. GC
