Would like to give my male Barred Rocks to a friend or put them on Craigslist. Out of the 7 McMurray sent me in the "special mix," I think 6 are boys! Can you please confirm? First pic is all 7 together. Clearly, 4 are super light, two are darker, and one is almost all black. I've put them in number order from lightest (most likely to be male?) to darkest. Don't want to give away any girls as I think I've had horrible luck already with Straight Run! And at 5 weeks, can I offer them for free on Craigslist in groups less than 6 for local pick up?
