Unless that dear is in a wheelchair, I don't think an 8 inch fence will do any good.Do you have to have an 8'; fence to keep a deer in Arkansas?
why do you want to keep her? She is wild,beautiful yes, but wild, and she is meant to be free. Set her Free!!!! De p.s. I dont think an 8 ft fence is tall enough, boy they can jump!
