Cool thanks. Because production is linked to inbreeding how important is uniformity of non production traits in relation to production? If all things being equal could breeds like Icelandic and and Swedish flower hens be as productive as a standardized breed or is there to much genetic material...
Out of curiosity if one used a supposed landrace breed like say the Swedish flower hen. They could technically be thought of as mutts but do have some commonalties in shape and size.
Selected only for utility traits would it possible to maintain high egg and meat production at the cost of all...
