I got 9 bantams at Tractor Supply. Straight run....eeek! I have no idea what they are. I have five dark ones that all look the same, three lighter ones that all look the same, and then one that is unlike the others, and light as well
I have 2 bantam chicks I got from TS on Thursday.
I learned that Silkies have 5 toes, black skin and feathered feet. One of my chicks is a Silkie.
The other one has feathered feet, 4 toes and light colored skin. It’s a Cochin (aka Pekin).
I believe your last photo is a Cochin chick.
Look closely at them and you may be able to ID any Cochins or Silkies.
Bantam Brahmas also have feathered feet but they look different from my chick.
Hopefully others with more experience will chime in.
Also, Google “Meyer chick identification”.
They have photos of tons of chick breeds.
