I know they are different breeds, but my RIR and SLW have wattles that have been present too. With the Australorp, I am watching the feather pattern and comb. The feather pattern looks just like the pullet on the Meyer Hatchery site.At 11 weeks old, I still think male. On most pullets the wattles are about the last thing that develop. This 11 week old chick has wattles.
Your pictures look female.I'm leaning girl. Heres one of mine that everyone said was a boy. Shes now 25 weeks and laying.
