I lost a bird this year becuase she got pecked really bad in the head. I had to move her into the brooding pen until she healed but she was kind of off, mentally, even after she healed. Then one day I found her in the next box with my mean brooding hen (who had raised her). I thought it was odd that she would be in there because my brooding hen is so mean....well, she was dead. My brooding hen pecked her to death.
Do you think she tried to stay in the nest box becuase the brooding hen was her surrogate mom as a chick? It was really sad. She was one of my own chicks that Big Boy fathered before he went to go live with Robin. Boooo
