One more - black roo breed ID?

[mayabear13]

I think we've figured all the chicks except this breed. Any guesses? They have some white feather tips and are slightly smaller-framed than our BO and Australorps.

Here he is at 1 week

And at 6 weeks

Thanks!

Wrong color legs for a leghorn- I'm guessing Black Minorca possibly, if the ears are in fact white.
