Our chicken has been laying beautifully for about 1 1/2 months but over the past week has been laying in the poop pile under the roost. I have plastic eggs in all the nesting boxes. How do I change this behavior??? It makes egg collecting a little gross when I have to fish it out a pile of poop. Plus sometimes it breaks when it lands and so it is cracked AND in a pile of poop so i just throw it out. Please help!
