My barred rock, Penelope, just started laying this week. Her first egg was a medium sized egg, which I've heard is normal. Her second egg was laid in the morning, shortly after I had gone to work (I heard her, but couldn't be late for work), by the time I got home, the flock had eaten it, and since then, I have not heard a peep from her. Is it normal for them to have a 4 day or longer span between laying, or is she laying them while I'm at work and eating them? What do I do?
