Brown shell

Brown egg programs include hybrids that may be sexed by the colouring of one-day-old chicks or by the speed of feather growth. They are created by crossbreeding refined lineages of the Rhode Island Red, Sussex and Plymouth breeds. The colour of the feathers may vary from white, through amber or Sussex marks, also red, brown, blue and black, barred or not barred. These programs are also used for feeding roosters on the principle of dual-use poultry for the production of popular traditional meat with strong taste, very different from ordinary broiler chickens.
