Before suddenly being lethargic on Thursday, no. She was just as active as the other girls and even laid an egg the day before and was acting completely normal.
Unfortunately, she passed away Friday evening.
UPDATE: We got a 16 gauge 1" needle to drain the excess fluid. What came out looked very much like egg yolk (picture inserted) and that's as much that came out before stopping draining on its own. Her comb has gained some color back but I'm puzzled about the substance and don't know what to do...
1) What type of bird , age and weight (does the chicken seem or feel lighter or thinner than the others.) Barred Rock Hen / 1 year old / chicken is swollen and puffy
2) What is the behavior, exactly. Lethargic, water coming from the mouth, comb turning purple, diarrhea, abdomen severely swollen...
