Fantastic ! I bet you're very happy now. Is this your first hatch, I can't remember ?
The white spots on the head only indicate males if the mother was barred or cuckoo and the father was not. If the roo was barred or neither parent was barred, then the white dot doesn't mean anything WRT sex linking.
Yep, its my first hatch and first run with the cooler-bater.....Cream Crested Legbars have the white dot/black dot sexing....if you want to see some interesting genetics....look at how they made the CCL s.....much prefer olive eggs than another adolescent boy yanking the feathers out of the girls heads....
