My girls completely disregard the fences we have up... They just fly over or actually climb the fence to get out of their open space and join us on the deck. And my two EEs think our deck shelves are perfect for laying eggs. They will jump up to the lop levels (its 6 ft!), push the items on the shelves off, scratch up the wood and lay an egg (which will sometimes roll off) Crazy girls. So, since I can't prevent them from doing this, I moved one of my egg boxes (which they were ignoring in the coop) to the top shelf, and voila, now we have chickens laying in two egg boxes. Its not safe from predators, but since I work at home and rarely travel, I can collect every day. I guess if you can't beat 'em, join 'em!
