While EEs are not an stablished breed and any color can be expected... That rooster tells us many things about his genetics just by looking at him.
His phenotype is what we call Black Breasted Red or Gold Duckwing. So at the very least he is wildtype on just about every known mutation, should eb/eb at the e locus.
White Leghorns hens are E/E(Extended Black), B/-(Sex linked Barring), S/-(Sex linked Silver) I/I(Dominant White)
The result of such cross will be E/eb, B/b+(for males and b+/- for females), S/s+(s+/- for females), I/i+(Dominant White heterozygous) So basically All white birds with some black specks.
Black Australorp hens are E/E(Extended Black) and everything else wildtype so the result of such cross will be E/eb, All black with some gold leakage when adults
Cinnamon Queens/Isa Brown hens are eWh/eWh, Co/Co, s+/-, I/i+
The result of such cross will be 50% eWh/eb, Co/co+, s+/-, I/i+ Will look like bearded Cinnamon Queen hens/Roosters. 50% eWh/eb, Co/co+, s+/-, i+/i+ like Cinnamon Queens with black feathers instead of where the whites feathers are
