New Member and a Question about coop size to number of chickens

[bluegreenmarble]

Thanks! Since there are 4 roosting branches in the coop and 5 nesting boxes, not to mention the funny connecting box that connects coop to run and a large run, I think I am looking good space-wise but whoever said to be careful adding to the flock peaked my interest. They are such a tight little group. 7 might be plenty. Might need to move on to ducks. Greatly appreciate all of your help!
