I have A fake egg or golf ball in most of the nests. Sometimes I think I have a bunch of eggs, only one is an egg. Someone moves the fakers. Had a BR broody that stole the other broody's eggs.. they were marked.. I think she is the golf ball/fake egg thief tooI do know my silkie cross/cross will move them around. I picked one up and put it out of the way by the door only to find her scooting it around.
