You have to realize that Abula is only 14 years old, that explains a lot.
Its not huring her feelings but you don't want her wasting her energy trying to build a nest for chicks she is never going to have and like Pat says the very act of egg laying takes a lot out of them, you want to avoid that if at all possible.
I love the innocence of some of your posts, no one else but a youngster would ask some of those questions but I enjoy answering them and I think a lot of others do too so ask anything you want.
