I can't speak for Meyer's...I'm not even sure where they are located or how long it will take for the chicks to arrive. (I will be looking them up in a second.)
I can tell you for fact thought that since you are located here, if you ordered chicks from Ideal they would hatch on a Wednesday afternoon and be at your post office early Thursday morning. Which I think is fabulous, to be able to receive chicks that young.
I don't think I would ever order from a hatchery out of state because I would be too worried about them taking too long to get to me.
