Need help figuring out breeds

[Elf2004]

They are just over 5 weeks old. Any idea on breed? Here are current pictures and some from when they were younger.

The red one looks like a Production Red or Rhode Island Red.

Lots of birds look like the grey ones.

Where did you get them?

They were purchased by the school I work for from tractor supply. The person doesn’t remember the breed. I have two gray ones at home. One is a blue rock and one an Americana. This one looks different. Do you think maybe a Sapphire Gem?
