Please let me know if you see any rookie mistakes in the tractor we've planned. I'm coming up with the general idea and it is my husband's job to make it work, bless his heart. Run 4x8 feet Detachable coop 3x4 feet 7 feet of roost inside 5 feet of roost outside ramp slope about .7 No, I don't plan to put a purple roof on the coop...unless 3 tab comes in purple. Here are my questions 1) I plan to have two roosts perpendicular to each other and one slightly higher than the other. See green crayon in drawing. Is that a bad idea? 2) I plan to put four 6 in x 12 in soffit vents in. (The drawing is wrong.) Two in the front, two in the back. Is this sufficient for the pacific northwest? 3) Is 6 inches off the coop floor too low for next boxes? 4) Is the roost in the run a bad idea? It will be 2.5 feet off the ground. Most tractors I see don't have a roost. Thank you for your help!
