Sorry to hear about your loss! Have no idea what it could have been. I would just suggest, that if next time you see one of your birds getting sick you'd seperate it. If it is infectious you at least hopefully won't spread it to the rest of your flock. You can always try a round of antibiotics then and see if it gets better. Sometimes something goes on inside of a chicken and youll never find out what it is, unless you do necropsy. Is not cheap though, so if only one chicken is affected, might not be worth it
