Sorry I was just always told that they could die in two days if they had an egg stuck I did check just now and she doesnt as far as I can tell and shes 7 so she hasnt layed an egg in a while.
The two day thing is not true and I have necropsy pictures somewhere that show that. Check inside her vent for small pimple like things, that's cancer and it's very common in older hens.
