With such young chicks,, sometimes it gets challenging trying to id the breed.
Unless someone is breeding, and hatching such.
But do want to welcome you to BYC.
The feathered legged ones with a bug fluffy-er of faces are millie fluer d’uccles. Your little yellow chick could be an easter egger as it had a small crest. I have never seen a little bird like that before! It will be super interesting to see how it grows
I don’t see the crest but if it gets one it is a pyncheon bantam. If not it is a wheaten old English game bantam. I agree about the breeds of the other chicks. I think I see two d’Anvers as well
