It won't hurt anything to raise your pannels high enough for the chickens to get in. The whole bear fence idea is based on the idea that you have to lite the bear on the nose, before he gets his head past the wire. If you bait the fence, he won't be looking down before he gets educated. How did the pannels work for you? I have thought about these, only placing them around a flatbed on a running gear, so it's portable. It'd be nice for those little pollination jobs.
