So I am about to move forward with the last phase of my chicken run design - the roof. I have bought a few flexible pvc sticks and am going to create a dome over my chicken coop. This will provide a covered roof of sorts for the run. I bought black nylon bird netting. I need to use the netting in one 5 foot section because I have an apple tree and this will allow me the flexibility to wrap around the branches of the tree. To give a better description, My run is 26ft long and 4ft deep. The leftmost 12 feet has no obstructions. Then I have the 5ft wide tree and then no obstructions for the last 9 feet (but this is where my 6ft coop is. So I have to create a dome over the top of the coop. But I could hypothetically use chicken wire over the pvc dome as a roof. This would still leave that tree section having bird netting exposed to an animal getting through. So it could have chicken wire for the left 12 feet, then bird netting for 5ft and then chicken wire for the last 9ft curved as a dome. Is it worth this trouble? Should I just use the bird netting for everything?
