My chicks are 4 weeks old, so I could be very wrong about this, but my man Merle checks almost all the boxes for being a rooster. I’ve uploaded some pictures of both Patsy (my barred rock pullet) and Merle (my suspected cockerel). The first two are of Patsy and the second two are of Merle. I’m pretty confident in my assumption, but it’s nice to have a second opinion.
