I’ve had ALL kinds of trouble with a couple of hens who like to use the shelves on the back porch as nesting boxes. This past winter, I started stacking wood in there, which put them off for awhile, but this one hen has returned, determined. Now she’s managing to get up to the highest shelf. And she leaves me an egg there every day. BUT. I don’t want her there! And so, the game is on again.
By the way, if you look here, there’s a cute little video of one of my hens laying an egg on the shelf last year.
