Where are you located? If you lose her and want to find out what was wrong, your state vet can do a necropsy and testing. Here is a list of most state vets to contact:

Sorry to hear about your flock. Sorry if this is a silly question, Is she not getting enough air because she’s sitting or a result of whatever is going on?

No clue but i just know that the purple is because she is not getting air. All chickens when can not breath there skin turns purple

Heart problems or not enough oxygen getting to the lungs may cause the discolored comb. Is there any gasping or an enlarged lower belly that could be ascites?
