My BA started back to laying a couple of weeks ago but for some reason she refuses to use her old nest box. WHY? I have been getting eggs off the nasty floor of the coop so a few days ago I put stuff in there so she couldn't make a nest. This morning I found a filthy dirty egg behind a container on the ground and another one under the steps. I moved the nest box (which is full of nice, clean pine shavings) to another location and made it as private as possible for her. What are the odds of her going back to it? And I sacrificed the two dirty eggs, marked them, and put them in the box. Think that will help to encourage her to lay there?
