One of my RIR's has been laying for about 1 month now. She has laid 1 egg every single day up until Sunday. She did not lay Sun, Mon, or today. They do free range but only right around the house, and I have looked everywhere. Ever since she started laying even if they are free ranging she has went to the nesting box. So I am wondering what is going on. No fart eggs, all large and 1 double yoker from her. What could the problem be.
