What is it?

[Pinsprings]

A friend found this chick in their yard 6 weeks ago, couldn't find the owner and gave it to me. It was very tiny when I got it but not as small as newly hatched bantams. It seems to be developing very slowly.

Leghorns are EXTREMELY small (bantam size) and of course have white plumage. They are common and I am almost sure that it is the breed.
