Do you have any pics? How old? When has she last laid an egg?

She was laying about 5 days ago but laying has been up and down as its been so cold where we are
Unfortunately she has just passed away in my arms she suddenly started fitting and then died
It was so sudden and I can't think of anything that she ate all there food is kept dry and there's no mould

Alot of fluid has come from her beak which must have been from her crop
