The more I research coops, the more I'm convinced I made a mistake in buying this coop.  Chickens need 1sqft of ventilation and this thing only has tiny holes that will not be enough. I'm only keeping 4 girls in there and it's totally not enough.  Also the roost bar is only a few inches off the floor.  Ideally chickens want to be up higher- around 24".  The roost bar is also plastic.  Also there is not natural light in there which chickens also like to have.  Ughhhhh....I'm so annoyed that I bought this stupid thing.  I've grown to really like my chickens alot and don't want to put them in this stuffy box that is not ideal for them.
