I agree...not looking like Leghorns...white Leghorns would be solid yellow chick down coming in with white feathers. Brown Leghorns would have been chipmunk chicks with a dark dorsal stripe coming in brown.
You've got red feathering on no dorsal stripe....I'm thinking you've probably have Production Reds.
As they are neither chick down nor adult feathers, but this awkward phase, it is hard to tell what they may be.
You will likely need to wait until the feathers fill in to see what pattern (or lack thereof) you've got to determine breed.
It is possible, but highly unlikely, that you got another Leghorn color than the traditional brown or white. There are a number of Leghorn colors, and one of them is red, but that is rare to find at a feed store.
I'll link the Feathersite Leghorn page so you can see the multitude of Leghorn colors, but in my neck of the woods, we only get the traditional brown or white at the feed stores. You have to go to a breeder to get additional colors.
