I have some hatchery buff orpingtons, whom I love. But their size and growth rate leave something to be desired and their laying is not that impressive. I would like to track down some dual purpose birds who have been bred with hardiness, good mothering instincts, meat and egg production, and good foraging skills; just like our great-grandmothers would have wanted. I could not care less about showing, and it seems like that is what breeders breed for. Do you know of some great production strains for Buff Orpington, Delaware, or Austalorp for the practical homesteader? Oh, does the white color of the Delaware make it more of a target for predators? My birds free range during daylight hours. Thanks.
