chickens and eye color

[kwynn's birds Alaska]

I never would have thought of this before yesterday, but should chickens of the same breed have the same eye color?

I have 6 black australorps. 5 of these girls have deep brown eyes, while the 6th, has more orangey brown eyes. it dosn't really matter to me what color their eyes are, as long as I keep getting eggs, but would it matter if they were say.... show quality? just wondering

It only matters if you are into breed preservation or showing.
