Very good point about the size plywood comes in. Mine was built by a friend retired builder and he adjusted my plans to accommodate sizes materials come in.
My coop is smaller 5 feet by just under 5 feet and a little over 24 inches elevated - it can be a back breaker to rake/clean under that. And if you have to catch a chicken under there ,you get to lay in the area .
If possible you may want to give it a little more height to ease those chores...
out of ovations :(
Didn't think about then nest boxes 'cause mine are.
But I would add to the Good: easily removable roosts to clean or replace
And to the Bad: no crevices in the coop you cannot clean easily.
Hi, sorry I missed your new member post, so here's my welcome .
The Good :
Wish I had room to add under the roots poop catchers - but my coop in GA is bedded all in sand, so not a big deal here. I think the original thread was called " lotsa Poop" ? Basically rectangular trays with sand...
