Sexing Braekel and Paduan chicken...

[Catus]

I have 2 cute chicks, one is Braekel and second is Paduan (a day younger).
Do you have any suggestions how and when I can determine their sex?

I already have a rooster, but he seems to be infertile (SLW of unknown age, maybe 3+ years), as none of the eggs my hens have tried to hatch have shown any development.
Anyway, I hope I have at least one pullet, but I think they are a bit too young to tell the sex.
The brown chick is Braekel and about 10-11 days old, the yellow chick is Paduan and about 9 days old.
Any thoughts?

Far to young. Try posting pictures at around 6-8 weeks of age.

More than year has passed and I found my old thread again. The two chicks are grown up and turned to beautiful hens, both are good layers and surprisingly good flyers, even the Paduan hen.
I just bought some new chicks and again one Paduan and one Braekel. This time I could choose myself and actually the Paduan chicks were rather different from each other: some had larger and not so round buffs on top of their heads, some had smaller and more round. Braekel chicks differed also by their combs. They all were less than week old, so definitely too young for sexing, but I tried to choose the most female-like chicks. I took some photos and when the new chicks are old enough for clear sexing, I will post young chicks photos and near-mature ones.
Maybe it will help someone like me who has little flock and tries not to have many roosters.

Post some new pictures if you can. I'd sure like to see how they turned out.
