I am planning to start building my first coop. I am thinking about 4x8 with roof tall enough to walk around in. I know I will need ventilation but is there anything I need to know about how I decide to layout the coop. My initial plan is to have nesting boxes across the back that I can access from the outside. I know I will need the nesting boxes, roosts/perches, ventilation, access doors. I just don't want to screw up and learn after the fact that I should not have windows near a nest box, or that perches need to be higher then the vents, or anything that they might not like. I am assuming that they will adapt to about any layout as long as they have the basics, correct me if that assumption is wrong. Right now my plan is to have nesting across the back (8 foot wide wall) and then on one end have an access door i can walk in. Then on the other end have a door I can open and reach in if ever needed and to help cleaning. Probably a couple windows along the back above the nests and a small window on each end. Not sure if I need to position the perches inside in any certain area in relation to the nest boxes, windows, etc. or just make sure they have some place to roost. I am thinking the interior should be laid out in a manner that is convenient for me.
