I am also located in Australia. Thanks for the reply. Some of the hens are showing some of the signs you have mentioned. They may not lay now, or straight away, but at least I can be sure that they may lay in future. Thanks again for the reply.
I have a few pullets, most of them nearly 9 months of age. Some of them have large dark red combs and wattles. My blue Australorp, my welsummer pullets and Gold Laced Barnavelder have nice combs. When will they still start laying? Please see images below.
