I would love to figure these cuties out.

[ChicksN Coffee]

My wife and I picked out these cuties at our local Tractor Supply Store here in town from the Pullet bin. They told us that they are a mixed group of breeds in there and now we wish to find out what breed the are. 2 are brown and 1 is yellow turning white. As you can tell by the pictures their combs are starting to develop.
Can anyone help? I have looked over the breeds and with these girls only being 13 days old today ( from what the girl at the store told us), and us being so new to all of this.... we are confused and excited!
Thank you in advance

Here are the pictures of Mildred



Here is the picture of Ethel


This is Tyson Girl

The two reddish ones are likely Production Reds, and Ethel looks like a probable White Plymouth Rock.

I'm leaning towards Production Red on Tyson Girl and Mildred. Ethel could be a lot of breeds, since white chicks are hard to identify.

Mildred and Tyson girl look like Production Reds. Ethel is likely either a White Rock or a White Leghorn.
