Is this pretty accurate? I've read that roos feather out later than pullets. I have 2 chicks that are a week and a half old. The SLW has plenty of wing and tail feathers. The GLW has small wing feathers and no tail feathers yet. I'm giving my packing peanuts to a friend and am wondering if I should give this chick along with them. I can't have roos and my friend is out of state so I'd like to weed out as many potential boys as possible The GLW also has some pretty stocky legs...I can put up pics soon.
