What’s going on with her underside?

Hello! The pictures attached should be pretty clear but what’s going on? A few days ago the chick looked fine (and the others are fine today) but this one has a really swollen rear end. Any help would be appreciated!

This could be a hernia.

Oh poor baby. I think only a vet could confirm that, but at the rate that it grew, I would be concerned. My first guess is hernia, some sort of infection, or a fluid build up.
