They are way to young to tell.
The one with the dot looks like the hatchery marked a certain breed or gender for you if you had them shipped to you. Or they marked them for the person you got them from.
Cute little puffs is about all I can guess at this point. Sorry.
I was told by the hatchery that the chick with the blue dot was either a red sex link male or a white leghorn male. That makes the other one a buff Orpington
