I noticed this today on my Ibera ... I think I noticed it before but much smaller a few years back ... she is a prolific egg layer this one and she is acting gravid at the moment ... hoping this photo link will work

She doesnt seem to be in any pain, and she is very lively , eating etc and has been mounting the other females a lot! Mebbe that is a clue?
Not sure if I should do the sugar water thing if its still up like this tomorrow?
Any advice gratefully received thanks
