"Big" brother is drop dead gorgeous as well... Had you posted pics of him before? If you did I (unfortunately) missed them!
This kid doesn't eat like a runt, that is for sure! I have a feeling he will catch up, no problem. He has been out in the yard to graze a couple of times, and he loves white clover and dandelion.
I keep looking at the one you posted up above, with all that gold coloration - simply amazing how vivid it is.
