What breeds are these and which are laying?

[heartsfromiron]

These are pictures of my chickens, I've tried guessing which breeds they are but I can't really tell for sure and I want to know.

And these are just 3 of the eggs I've gotten from them, I was wondering if there's any way to tell which chickens are laying which eggs?

Not sure about that first black one. Is it really speckled with white, or is that just the lighting in the picture? If it really does have white flecks, then it could be a Mottled Java.
The solid buff ones are Buff Orpingtons.
The red and white ones are Red Sexlinks.
The white one with black in the 3rd pic is a Delaware.
The black one with feathered feet is a Langshan.
The ones that are laying are probably the ones with the biggest, reddest combs. The ones that have slightly pink combs are still a few weeks away from laying.

Thanks! This was really helpful, and also the first black chicken is the same one with the feathered feet, so you answered your own question!

Glad I could help.

I agree with junebuggena.
