The little brown ones with chipmunk stripes looks exactly like my silver penciled rock roo looked when he was just hatched. Sometimes as chicks different breeds can look very similiar and can be difficult to tell the difference without a trained eye and subtle clues. Did you get any bantams? The same chick is also very similar to my partridge silky coloring. Didn't they tell you what's what? Did they sex them? Just curious we don't have a big r where I live. They sure are cute whatever they may be! I'm sure they will bring lots of joy!
