my last americana I bought for 2 bucks in 2000 is vary sick most likely cancer. the chicken has seizures when you pick it up. if you don't touch it it seems fine. it goes to bed at 4 pm when its still light out. so ill say 15 and 1/2 years old as i don't think it will live much longer. this chicken has lived two chickens worth of life. never was much of an egg layer and i only feed it organic laying pellets.
