With a base of 10 x 10 would consider it a Smaill coop... And the Arc is Cattle fencing ... Cattle fencing and sides covered with chicken wire and a door to walk in the front and the nesting boxes have lift up covers ...

When I charged my friend with coming up with a design for my coop, My two criteria were:
1. I needed to be able to walk in and clean it standing straight up
2. I wanted to be able to get the eggs from the boxes with out going inside the coop ...

With those two things and the fact that I wanted to keep the cost down, many other great pluses came from this coop ...
1. It is a mobile coop ... I was able to move it by myself with a little of Egyptian ingenuity
2. It only cost a total of $225 in materials
3. If for some reason I am done with chickens it would easily be converted to a green house with some plastic sheeting ...
