Childhood nightmares!
My family had commercial chicken barns for 50 yrs.

Chickens do not have sweat glands so it depends on what climate you are putting them in.

If they get too hot they expire.
Climate control is most important.

Cleaning the barn floors is a real pain in the ass so design doorways large enough for a mini skid loader.

Hanging waters and feeders are much less clean up and trouble, gravity feed.
You can move them out of the way for skid loader to clean floors easier. Less work.
If you are in area to have to temperature control, window curtains on auto temp control to open an close. If you are year round perfect climate no worries.
Rat control!!!
You put out the feed and they will come!😂

The door of our chicken barns, which are now hay barns, still has the permanent ink my deceased Son wrote on it.
It says:

I HATE CHICKENS!

well boo on you, chickens "hate" you too then!

so late the game to let your true colors
pop out there Nana.

an egg offers a delectable amount of protein in comparison to a.... let's say grasshopper!

Yepper dont care if they hate me too!

If you had my experience with them your whole childhood 7 days a week for years you would hate them too.
