Does anyone know where there is a reference chart with weight sizes on it? Is there such a thing? What is the difference in size from cochins, OEGs, japs, etc.? I've heard Dutch are smaller than OEG's but the ones i've seen look bigger. About 20 years ago I had a little wyandotte hen that was from a hatchery mix special and she wasn't much bigger than my OEGs, but from what I've seen they are usually much bigger.
