My 3 hens started out laying in the boxes, but now one keeps laying on the floor. I am thinking that it just falls out. They will keep going to the nesting boxes, but I'll still find one on the floor. Unfortunately one of the eggs gets broken almost everyday. I think it is accidental. They are driving me crazy!!!!!! I did finally put a new nesting box on the floor. A rubbermaid container with a lid. I cut a hole in the longest side. The hens love it. The one that lays on the floor scoped it out, but I don't think she used it yet. Good luck to you.
