Chicken breed questions

[AndrewP07]

Hey, in the latest bach of eggs that I got from a polish/sikly bantam breeder, there was one larger egg. It had a slight green or blue hue to it. I had a few eggs that looked just like it, and I'm not sure which chick came out of it. I do have one chick that came out of one of the larger eggs, and it does have extra toes, and I don't have any silkies in my flock. It is black, with feathers on its feet, and white wing tips, and a white butt. I’m pretty sure it came from her, unless one of my hens have silky in them, but I’m 99% positive they don’t. Also this chick doesn’t seem to have a Pom Pom on its head like the other chicks I hatched from her eggs.

Sounds like it's a silkie cross.
