Help with my Black Chicks identity

I have three black chickens that I thought were all Black Australorps. After reading this forum I question if all of them are because yellow on the bottom of their feet seems to indicate Jersey Giants.

Can anyone please clarify for me what breeds the girls are?

I got them from Mt Healthy Hatchery that sells Black Australorps, Black Giants and a Black Sex Link cross.

Here are the three as day old chicks:




At 2 weeks:



4 weeks:



Photos from yesterday Oct 26th at 18 weeks.

Rue, the bottoms of her feet are pinkish:



Walking away she is the one on the left, bottom of her feet showing:



Agnes:



Agnes bottom of her feet are yellow:

I couldn't see the bottom of Bell's feet, she seems very camera shy, but her body is different than the other two. She is very big and roundy, whereas Rue has the upright tail feather and Agnes looks like she is getting them.

Belle's comb is almost purplish looking.



Oops, somehow I posted this before I was finished...hence the editing.

Thanks in advance for any and all suggestions.

 

I just came in from taking care of the girls...brrrrr....and the bottom of Belle's feet are pinkish like Rue's.

Seeing her standing next to the Buff Orps she looks alot like them, big and poofy.

 

Thanks,
So there is no chance any of them might be the black sex link cross?

 

So do production Australorps sometimes have yellow on the bottoms of their feet?

I did. I said that the bottom of Rue's feet were pinkish and after coming in from that morning's feed routine, I also verified that Belle's feet were pinkish at the bottom. Only Agnes has yellow on the bottom of her feet.
