yes the north flock on my place has a white/gray hen in the flock she is 2-1/2 old, its odd for one to live 3 years but she has, most of the time bobcats or coyotes would have killed her but i saw her today, she is in a flock of 20-25 hens and she has made it for near three years, we had one on the south flock about five years ago for one season then she was gone, the south flock was bad about crossing the road, lots of road hunters.
