I am thinking of choosing a endanger breed of chicken to add to my set up. I raise Barnevelder's, Black Cooper Marans, and Serama's now with a mix's of layer hens. I would like to pick a dual breed that is a good producer of both meat and eggs. I like good temperamental chickens that are well mannered and not too flighty. I what to improve on the breed and try to get more flocks established. Anybody have a breed you would recommend or like? I thought of Crèvecoeur or Houdan but I know there are a lot more breeds in trouble too.
