If she's not drinking and eating, then she's not getting the extra calcium.I’ve been giving her calcium in the form of tums, crushed in her food. Although I tried to j keep her quiet and no more than dim light for most of each day, she has laid 2 eggs since I noticed her trouble.
I am very concerned about not drinking or eating.
I agree, you may need to tube or syringe fluids into her. The Tums doesn't dissolve/mix well in water, so cut it in pieces and just pop the pieces one at a time into her beak and let her swallow.
Hydration is extremely important, so work on that too.
She's been able to pass/expel 2 eggs with the prolapse like that?
