It is as austrolorp about 4 weeks old, it's the only one that has black and white feet and all black down feathers on it's behind.

Sorry I can't tell a thing from the pictures.

The leg color means 0 to me on sexing. I go by comb and wattles and feathers.
A better bigger picture of the bird standing a side pic showing tail and head. The leg color will change more as the chicks get older.

I agree, try to get a few bigger close up pictures and maybe a full body!
