I've had my chickens for a couple years already and they have a nice coop, but it's ugly. I found a cute play house on Craigslist that I want to renovate to make a nice coop. It has a door and three windows. I was going to put a nest box out of one window for easy collection and also not to take up space inside. I was going to put plexiglass over the other two windows, but I want to make sure there is enough ventilation. There is also an opening over the top of the door. How do I secure a nest box to a plastic playhouse? What's the best way to ensure enough ventilation? Would a picture of the play house help more? Thanks!
