My husband can't tell the two apart but the cuckoo on the left looks like the black and white are a tad blurry....like you need to squint to sharpen the colors?....the barred rock has a sharper definition between the black and white, and I think, is lighter. But the barred rock does lay a beige egg and the cuckoo on the left is a chocolate colored egg layer and she is larger although she is younger than the barred rock. Sometimes the cuckoo's eggs are really quite light and hard to tell from the barred rock's. It's like her egg coloring doesn't work well. Then there are days where they are spotted! Neither of these is breeder quality.
