Feel this is a more expensive card board box, I embrace the idea just not the full design. Sure its easy and cheap, but really lacks in many departments. For one the ventilation idea seems like an after thought and seems poorly thought out. Ease of design and construction along with cost is awesome. In my humble opinion a roof should be a roof and chickens prefer side angles versus over the top predatory 'surprise'. Checking the nest box seems like a task, clean out...another task. Just leaves me with an over all 'Lets convert my dog house to a chicken box and call it affordable'.
