Glad to find out they are dark brahmas. I have one, also, just a little older than the one in bleu chick's picture, but I couldn't figure out what it was because it's not in the Murray McMurray catalog (which is where the herd came from). I saw the feathersite photo earlier today and thought it must be a dark brahma rooster judging from their photos, but it looks more like bleu chick's.
Bleu chick, whatever you have, I have, too, and we're both wondering why we have them!
