Trying to figure out what Breed I have

[Mikedero]

I posted this before but in the wrong section so I figured to try here instead. I know I have 2 Cinnamon Queens. But the other 6 are bought from TSC. All 8 are the same age now at 5 weeks old. Here are a few older pics I will try to get new ones. But just to let everyone know they are not even a pound yet at 5 weeks so I know they are not Cornish X, I was told be a friend that is farm vet and by the store TSC that they are leghorns.

here are some pics over the last 2 weeks reminder they are all about the same size and weight.
