This morning I woke up to go check on my hens. Then, the unexpected happened. I found my hen under the chicken stairs, dead. She was prefectly healthy last time I saw her. Half of her skull and both of her eyes were missing, and her legs and feet down the the bone. What could have killed her? My other hen and rooster are fine. I relize the other chickens might have pecked her after she died; but when I went into the coop to grab her, my rooster attacked me. Again, what might have killed her? I am determined to get revenge on whatever killed her, so my other ones don't meet her fate. Thanks for your help.
