first, I thought sex links were standards, but that doesn;t matter. Put something where she likes to lay, so she can;t lay there anymore. Put golfballs in the nesting boxes, b/c hens like to lay where there are other eggs, she will think the golfballs are eggs. Is she being pickes on by the other hens? this could make her try to stay away from them. Ohter than that, I dunno.
