In some hens, the egg-laying process goes wrong. Egg production falls or stops, there is a messy, odorous discharge from the vent or the bird's abdomen swells. This article looks at several egg-laying disorders, their possible causes and remedies.

Its better to isolate the infected / diseased birds from the healthy ones at the prior time!!! its always better to diagnose the problem at earlier stage, then do treat the birds with Calcium gluconate and don't forget to postmartam the dead birds, because it would give you better idea of diagnosis and treatment accordingly.
In the treatment you can do the folowing things. Add more fiber to feed. Addition of sodium bicarbonate in drinking water or feed give calcium gluconate in drinking water
