I have a 7 year old half naked neck, half white crested black polish. She broke her leg last year, I though she would be a goner, but the leg healed, and now she walks with a very slight limp, espectially if she's running. I hatched one of her eggs this year, and have a nice pullet from her. I'm glad, as she's been a really good layer, and fun to look at too. The chick doesn't have the naked neck though. I have two of her half sisters, same crested mom, different father, and all three of them are 7 years old and really good layers yet. I hatched one of her sister's eggs too this year, and it came out blue, as the father must have been my Americana rooster. It has the puffy check feathers too.
