I have two beautiful black Orp girls, one of whom just started laying this week. Katia clucks and grumbles, but does not sing the egg song. She has, after much fussing around, scratching and rearranging of nesting materials, produced four lovely little eggs since Sunday. I thought it was odd she wasn't singing about it, but decided she had the right to be an individual. Yesterday, I heard the egg song, but it was coming from her friend Valentina, who was pacing back and forth in front of the coop, doing Katia's singing for her while Katia laid. Valentina has not laid yet, but she sure has the song down! Any one else had this happen?
