Very thorough with adjustments for all situations. I have 7 mongrel 'garden' chickens and 3 big fat Orpingtons. I had to take down a divider between 2 nest boxes to accommodate hens that cover a 9"x15" area when sitting! They're all in the coop at night & free range all day, with access to the coop. The 'jardineros' like to roost in trees during the day if it's hot. Over the past 9 months I've made a few changes to the coop to make life easier for them, especially in width of ramps in the coop for the Orpingtons.
