Ok, so I built a coup for my chicks before ever coming here. I found out after the fact that it was too small. So I am planning for coup #2 now and need it to be ready for fall. I want a 6' x 8' coup built on skids. I have some details that I am not sure of so I thought I would ask everyone here for the firsthand knowledge. My questions: 1) For a 6' x 8' coup can I get away with building it on 4x4 skids or should I really use 4x6 or bigger? I plan to build the coup and then drag it to the spot I want it. Beyond that it is not likely to move for a very long time. 2) Do I really need to put hardware cloth on the bottom of the floor to keep mice/rats out if the skid foundation is flat and not raised off the ground? 3) I was thinking of using 2x3's instead of 2x4's, 2 foot on center for the walls. Is that a mistake? 4) I like the looks of t1-11 siding, but it's like $27 a 4' x 8' sheet right now. Since I also want to insulate it and finish the inside I was thinking about using luan (1/4" plywood they use for sub-flooring) inside and out. It would be painted so I am wondering how well I can expect luan to hold up if I make sure to keep it painted and protected. Luan is about $10 a sheet right now so the cost savings is significant. That is all I can think of right now. I want to do a BYC page on this one since I am drawing up dimensioned plans and want to really plan this one out before starting.
