These guys were hatched 5/5/11, so just under 8 weeks. My first run at having chickens, I went up for four GL cochins and came back with three of these guys too. Spent all day oogling over everyone's BCM photos. Nobody has one with a mohawk in the rear. What's up with this guy/gal? Will the feathers lay flat with age? Is it the sign of a roo? The one of me holding it is from last week, rest are from tonight and it looks like a walking wedge of cheese. The three have almost no coloring and I'd like to separate and give the boys away before they start agitating the neighbors.
