Our black Australorps looked just like that! Tiny white tips on the wings when they are chicks. We have one that has markings that looks identical to yours!
I think she is an australorp, I think the only other thing she could be is a jersey giant, so just to confirm you can check the bottom of her feet. Pink equals australorp, yellow emails jersey giant! But she looks like my australorps, such cute and funny birds!
I went through the same problem until I looked at the feet. the above post is right. Yellow feet is Jersey Giant and white feet with pink pads and some pink showing between the toes is australorp
