Ours started laying under the nesting boxes (they are raised), the space in the coop furthest from the door and where they could watch the activity and feel secure. I covered the area under the nesting boxes so they couldn't lay there and put the eggs in the boxes to show them. They eventually figured it out. We have 7 nesting boxes but they only like to lay in just one. Sometimes I will go in there and find two hens stuffed into one box, laying their eggs! We have some new pullets who haven't started laying yet (19 weeks), and I am curious to see what they are going to do.
