We purchased this coop several years ago. We built a platform and then slid the coop off the truck on to it. The first pictures are of the coop shortly after we got it and the 4th is the following summer. I do have real steps now! It currently contains 7 chickens and you guessed it, I want more. Maybe 15 eventually. The run is built off to the right, so I'm thinking expansion should be on the left side. The interior pic is of the left side.I did add insulation and covered with board on inside, but nest boxes and board should be easy enough to take down. Any Ideas? Thank You!
