I just skimmed the replies, so maybe these points I get mostly from the drawing have been addressed.
You've got sections for breeds, and state one cock for each breed, but plan on letting them mingle?? That doesn't make sense to me.
If you plan on "maintaining the genetics that made these breeds" breeds need to be kept separate...with maybe another enclosure for cross breeding.
The hens with chicks section....do you plan on using exclusively broody hens to increase your numbers? Might be rather 'optimistic'...and multiple broodies with their babes will not necessarily co-exist in peace.
Yes, 18x18x18 is rather large for nests. 14x14x16 has worked well for me including Brahmas. 1 nest per 3-5 birds is plenty. No matter the amount of eggs they may lay annually, they still only one per day.
GA will probably need massive ventilation. Tho your floor plan is a good working drawing, I see few construction details, tho saw something about concrete blocks.
Do you have any elevation drawings?(old drafter here)
There are 3 great reads that all beginners should read linked in my signature.
Let me know if you can't see or access links.
