So I've had hens of all ages and one chick (three weeks old to be exact) to fall over dead for no reason. One day they are fine in the morning and usually in the afternoon/evening I find them dead (or a family member does). They show no signs of infestation/trouble and no injuries of any kind, so could it be an internal thing? Also, some of the bigger hens had shrunken combs. Is that a sign of a disease? What is happening to my hens, and how can I prevent it? The chick died yesterday, we had a big thunderstorm but my brother saw what happened. He said the baby fell into a slight dip in the grass so he picked it up and the chick started to close its eyes for no reason. Last thing I knew the baby chick died. PLEASE HELP!
