I read your other post to try and figure out what's going on. There could be only one thing or many things going on with your chickens by the descriptions of the symptoms you presented. You could be dealing with internal or external parasites, respiratory disease, overcrowding, too many roosters for your hens, feed issues etc....there's no telling what's happening without more detailed information. I agree with Flockwatcher that a necropsy should be performed.
