What breed of chicken is this?

[Shirou82]

A while ago, we decided to get a few chickens for a small backyard coop, after having to give away our flock several years ago due to predators and other problems at the time. We recently got several new chicks, and raised them from day old hatchlings about mid-March. We took in four white leghorns pullets, as well as two straight-run barred rocks. We also received two other chicks that were as well, but we are currently unsure of the breed. Currently, all of them are about 3 months old. Both of the unknown's started out as completely black chicks and had looked exactly the same. We originally thought that they were black sex-linked chicks. We did, at least, until one of them started growing larger than the other, and very recently began crowing.


This one is the male, with one of our barred rocks in the background, deciding whether to take cover under our truck

The female


Despite sitting still for a minute, she suddenly decided she didn't want her picture taken. This gives a decent view of her front and plumage, though.


This is a close-up of the male's feathers. Strutting around the yard, he is an absolutely gorgeous bird. Some of his feathers start out as black, but then immediately change into an orangish brown color, only to change back to black.


A small surprise was that both of them had polydactylism. This is a picture of the female's feet. She has 5 toes on each foot, while the male has 5 toes on one, and four on the other.

Thanks for your help!

I was preparing to question whether or not they have 5 toes on a foot as I scrolled through your post. They are silky crosses - dark skin and extra toe come from their silky DNA.

Thank you! We thought there was something mixed due to the legs. We didn't even think of checking to see if they could've been part silkie. We actually had silkies in our first batch several years ago, and that they were smaller than all of the rest of our chickens. Any idea what the other parent could've been? Our two barred rocks that were straight run turned out to both be cockerels, and the silkie cross is much larger than both of them, even though he is the same age. He also doesn't have any sort of tuft on his head that silkies usually have. Thanks
