Please slow down and think a bit more before advising.
The rule of thumb(minimal IMO) is 4sqft in coop and 10sqft in run.
Her light is on a timer....12-14 hours is the usual range... 16 is max.
I knew about the 10sqft per hen for run, but I have 7 hens that fit very comfortably in a 10 x 5 A frame coop, no problem. Also, I would say 12 hours is probably fine, but 16 hours is going to cut into their sleep. Now, I am only giving this advice because I have tested and proved it correct, but your are kind of the chicken veteran, so, what ever you think.
