My hubby got me these two ducklings and I am pretty sure from my research the little one is a Rouen but he bigger one I am not to sure. I was in the market at first to purchase a Khaki Campbell so the ducklings of that variety that I have seen were all much darker. This one is different. It has a large yellowish chest and a small crest. It is very outgoing and much taller than the other. Any ideas, I have done so much photo and breed browsing and I just can't be sure. The place they came from had a mix of ducklings so they couldn't be sure either. THANKS EVERYONE!
