I have a bit of a mixed bag of chickens aged between 10 and 14 weeks old. This australorp is 12 weeks ol d and has me a bit stumped about whether it is a pullet or cockerel. I have a terrible hunch it may be a cockerel - much more comb and wattle than its sister and thick legs but it behaves like the girls rather than the boys. What do you think? Would it be more obvious as a cockerel at this age? I know australorp pullets can show some comb and wattle at this age. Are these the start of pointy saddle feathers? The last picture is another australorp (same age).
