The 24" depth came after watching hens reach under the partition. I tried to find a length that would position the eggs far enough that they couldn't reach them. However, since adding the the curtain I've not seen any hens reaching under it. Perhaps that would allow you to shorten it. If you have 4" of box inside the coop, 4" of wall thickness, that only leaves 18" outside of the coop and could quite easily be supported and roofed without shortening my design.
When having problems with chickens stop and think, what would Harlan do?
I've dealt with many thorns in my life and the flower is always worth the effort.
