That is not normal.
The computer can make it hard to tell in pictures... I might see some lice type eggs on feather shaft in the bottom picture... or it could just be a bad looking sheeth. I would get a good check on everyone for external parasites, but this condition looks like more than that as
root cause. Do you have other birds? How old are these ladies? When was their last eggs? What is fed on a regular basis including treats and supplements?
It looks quite swollen... resembling possible ascites (aka water belly/liver failure) or maybe Egg Yolk Peritonitis... one link to check to check..

Sometimes relief is given by draining the fluid off the abdomen, there are threads discussing it if you are going to try yourself as many of us cannot afford veterinary care but will do our best to help an animal so we can carry forward that experience to possibly help others in the future. Said animals personal comfort is always considered first and sometimes culling is the kindest thing to do.
Bacterial (secondary) infections may be treated with antibiotics if one exists and may need a vets' rx.
Are they still actively eating, drinking, and pooping? How do droppings look? Color and consistency?
Rocks are some of my favorite
, despite my hatchery ladies having had reproductive issues too early in their life span.
Hope they recover quickly!
