not too sure if cinnamon and rosetta are the same thing where you come from (no such thing as cinnamon in NZ), but it looks like a rosetta to me, you can breed rosettas by putting a pharoah to a range (tibe). It's to do with a gene called extended brown that controls how far the darkest pigment extends down the feather shaft. My rosettas always look auburn to me compared to the range who look more of an ashy dark chocolate and lack the lacy pale edge to the feather. If you put this bird to a pharoah mate you should get 50% rosetta 50% pharoah offspring. If you put it to a range/tibe you should get 50% rosetta 50% range/tibe.
