My chickens are free-range. The neighbor's chickens are free-range and completely flighted. I've got a huge garden area planned, but I've got to keep the chickens out of it. Can anyone give me an idea of what I need to do to accomplish this? Our neighbor's chickens can fly into our 8-ft tall chicken run and eat the scratch we threw out for our chickens, so I'm worried about how to protect my garden.
