Might have been an egg song, even if she wasn't the one laying. For at least a week before she actually started laying, one of my hatchery EEs would hang out in the nest box and "false alarm" on an almost daily basis. She had me running in there to see egg color only to find no egg. Finally did lay a pretty green egg with brown speckles, though. She was about 25 weeks when she laid her first egg. I have another hatchery EE that is 27 weeks and I'm pretty sure she still hasn't laid an egg.
