Maybe a lil' Buff Japanese? I got him as a super small asst. banty mix from a feedstore that looked like that,he's the smallest roo I've ever seen. He's now as big as our 3wk.old chicksThe black could be a type of cochin,we also have lil black Birchen chicks just a guess.
Yeah, I'm thinking maybe a buff japanese and a black cochin, after everyone's suggestions an looking up pics those are my guesses. The little one is the noisiest little booger
And he/she is always climbing under one of the australorps-- too cute
I have a white chick that is as tiny as your buff one, from TSC. Even after a few weeks she is still so small. I am pretty sure she is a White Japanese Bantam, so maybe yours is a buff one.
