- The creator of the Rhode Island Whites wanted the two breeds to be similar in body shape so they aren't confused with the White Rocks. They have blocky body figures that are deep and broad. The males make great meat chickens due to their well-rounded breast meat. The breed is known for its great egg laying through the winter and being very calm and docile birds. *SOLD AS STRAIGHT RUN ONLY.
