White mark on 10 days old duckling feet

Hi Friends,
Can you please tell me what are these white marks on the duckling feet? Thank you.

Did they just happen or were they like that from hatching? It almost looks like nothing more than lack of pigmentation.

Sorry I just paid attention.
I am just worried if that is the sign of being too cold.
Brooder temperature is 70F with brooder plate.

I agree with @sourland that it is just random depigmentation.

However, I do think your brooder is too cold. 85-90f first week of life; 80-85f second; 75-80f third week. 70f is ok from 4 weeks old. Your photo looks like a 2 week oducklinging although I cannot fully see it to be certain!

It is coincidental that there is depigmentation: it is not caused by cold
