Hi -

I saw the following posts and they do not answer my question. I understand that egg count and light manipulation cause them to lay MORE eggs -- what I'd like to know is why an unfertilized egg is being layed in the first place? What is the evolutionary advantage to laying an unfertilized egg? Why do you chickens do it? (versus what causes them to do it more often). Thank you.
