I'm not familiar with this breed. I'm not sure how old. Does anyone have any clue if rooster or hen? I've got the chicken separated from my flock as he/she just wondered in my yard. I don't know of any neighbors around that have chickens so going to ask around tomorrow.
Breed doesn't matter so much when sexing when they've got those saddle feathers hanging down in front of the tail. Those are solely the property of males.
