I think you misunderstood.
I'm not worried that the egg tube is out. Egg tubes are meant to come out/drop. It comes out when she goes through her breeding behaviour, darker colors, egg tube drops, nest building etc.
I wanted to make sure her's looked healthy. Particularly the tip where it is blackish.. it has been this way since I got her, almost a year.
She goes through normal breeding behaviour, including her egg tube dropping she has just never laid eggs.
