Low Cost Preparation for Chicken Pasture

Sometimes the animals are not the problem. Keeping chickens on pasture means keeping them from flying out. I have noticed that chickens do not seem to fly over fences; instead, they fly up to a perch and down on the other side of the fence. I have a few handy perches to block them from using. Wooden fences and posts are enough of a perch for chickens to convince themselves that they can escape. I plan to put scraps of fencing on the inside of the wooden fence pieces to keep the chickens from seeing a clear path to a landing spot. A low cost solution.
