This chicken coop is 4 years old and desperately needs a coat of paint, but it is 3 stories with a place on the bottom in the back to introduce new chickens to the flock. It has two big coops which is the third floor, notice the little framed door on the side where we can collect the eggs. The other big coop can be accessed from inside the house. The big door on the inside opens the coop up completely for cleaning. We put plastic on this door and around the bottom in the beginning of winter and use a heat lamp inside the coop. If it gets below 20 we put plastic around the entire coop. Boy does it get smelly.
