So dad went to check on my girls and when he opened the door Rosa was laying on the ground dead. Rosa was like the only named bird. She would lay large, light brown egg. Rosa was the "mother hen" of the flock. However, over the past few weeks, she took to brooding and would not leave here nest box. Dad did some research and found that some chickens will starve themselves to death trying to hatch her eggs. She will be missed a lot.
