Hey guys I have to say learning a lot here. I have starting building my choop for my 11 chicks. It is 8'x8' by 4' tall.I hope this is big enough. I plan on building 10 nest boxes on the outside wall. Which I am wondering if this is enough? My roosting area will be 72"x48" with two 6' branches 18" apart from each other. I am wondering guys what kind of paint I can use for the outside that you would recommend? Thanks
