Hi everyone. Wondering if someone can sex my buff Sussex chicks - 7 weeks old. Thinking there is 2 pullets 1 cockerel and 1 I'm not sure! First 2 pics are of the potential cockerel, next 2 the one I'm not sure of, next 2 are pullet 1 and next 2 pullet 2. Not sure if it helps indicate gender but I also weighed them - cockerel 800g, mystery 700g, pullet 1 700g and pullet 2 650g. Thanks!
