Good observation. We'll done.She has most of the Cochin, the bright yellow feet (Also like the Brahma and RIR) with feathering, the light red coloring, the single comb, and the smaller size. But, she had the same black pattern on her tail as her father does, which couldn't have come from the red bantam Cochin side, so I think Brahma.
I also noticed that when comparing Yuzu's beak to her possible mother's beak (RIR), they look identical.
