Does this look like a Black Sumatra? There isn't much of a comb or wattles whatsoever and I don't see any spurs on the back so Im thinking it may be female. This chicken is almost 12 weeks old. Bottom picture is from when it was a baby chick.
I have a mystery chick that I was told was a Australorp when I bought it. I'm thinking it may actually be a Sumatra. It is about 7 weeks old now, and half the size of the other chicks of various breeds and the same age. The pics don't show that the feathers have a lot of irridescents The last pic is when it was 3 or 4 weeks old.
