Where does the “4’ per hen in the coop” rule really come from?

How did you make this?

It's three shingle pallets two are cut down to give a water run off. The forth wall will be the door and nesting box. Less than a hour of work. Will post more detail pics tomorrow.

Would love to see more pictures, plans, etc of how your coop came out!!! I'm looking at building another coop. Thank you!
