If you could get a better pic that would be great. It is not a barred rock and probably not an RIR. All the RIR crosses I've hatched have been solid dark yellow or red (not gray) and a barred rock chick would be black. I would guess Langshan, but don't they have feathered legs? Does your chick have clean or feathered legs?Dad is a barred rock and mom can either be barred rock, RIR, buff Orp or blue Langshan. I know it's not the greatest pic but does anyone have any guesses?
