I think its kinda hard to guess because alot of chicks look nothing like they will when they get their feathers. My darkest chick grew up to be my lightest chicken. I think that half the fun will be watching them change and trying to figure it out. But you should post pics right here in a month to see if anyone can guess then. You would have better luck. Let me know what you see in the eggs from my funny farm.
The black one looks like a Barred Rock chick-the others definately aren't Reds. The one closest to the front looks like a partridge pattern-maybe????
Hard to tell with many chicks absent some specific breed characteristic.
