Hi, I have a bluebell hen who is four years old, will be five Spring 2017.. I've done a quick google but the results say she should have only lived until 2/3 years old? Can't find much on the breed to be honest, just a few comments about the short lives of hybrids. They are a hybrid between RIR's and Marans. Anyone have one of these, I believe they are a lot more common here in the U.K? She is a house chicken now after a serious dog attack and is loving life, doesn't want to be outside any more.. Cheers!
