I am a new chicken owner, I have 6 pullets, approx. 3 1/2 mos old. They totally ignore the nesting boxes now. Will they eventually go to the boxes when time to start laying, when should I start putting fake eggs in boxes to coax them into the box? They will casually look at the box but dont sleep there. I have straw in the boxes. I also have pine chips throughout the coop.
