How many chickens?

How many birds would you have in this scenario. I currently have 7 and wondering if I have room for more in the coop at night given the space they have during the day. I noticed last night the girls cuddle tight and take up 1/3-1/2 of the roosting space.

Coop (only for night) - 4x6 - 24sqft - with 3 nesting boxes and 12 ft of roost space

Covered Run - 6 x12 - 72 sqft

Extended Run (Tree Coverage Only) - another approx 550 sqft
