Which breed will lay first?

[Quickster]

I have two barred rocks, two ISA browns, one New Hampshire red, and one amber white. I'm pretty sure they are all within a week of the same age. Who will lay first, next, etc? And if you have guesstimate ages they will start that would be great. I'm new to chickens. I have an idea but want to see what more experienced chicken people think.

I would guess the barred rocks or new hampshires will lay first. That's what I would guess at least.
