yes but do they sing this song before they lay an egg or after? and do they do this song every time
As I said in my previous post, "It can be before, after, or during laying, or when someone else lays. It can also be in answer to another's egg song." Also, nothing in life is guaranteed, so some may do it every time, some may do it initially and stop, some may sing sporadically when the spirit moves them.
