Australorp/ Jersey Giant Pullet/Roo?

[Manda0227]

Just wondering what everyones opinion is on this chick. She's 3 weeks old, is as large as the other chicks, but is the least developed (all day old when we got them). Wondering if she's a he and if she/he is an australorp or a Jersey Giant? Supposedly one way you can tell is the color of the bottom of their feet.

At this time I would say it is a Black Jersey Giant with it having Yellow on the bottom of the feet.

Now if it starts to get Red (lacing) in the breast then it is a Black Sex-Link...
