Our coop is 6x4 4 feet tall in front and 5 feet in back the run is 10x6 and the 6x4 under coop is available to them as well the nesting boxes are blocked off because they were playing in and starting to roost on them and I didn't want them to think this was the reason the boxes were there I don't know maybe I'm being silly but there blocked until they get to laying age lol we started with 10 girls 2 speckled Sussex 2 black sexlinks 3 Rhode Island reds and 3 cinnamon queens but one of black sexlinks was acting funny so we isolated her one evening and she had passed by morning so our coop now houses 9- 7 week old girls. This is our first coop and we are new to chickens so any constructive criticism or ideas will be great thanks for looking y'all
