Howdy, are you breeding for Blues? what are you using to breed your australorps with?I posted the idea that I have two Australorp hens that are sporting the chocolate color. Has anyone ran across this? I will try to get some pictures today of comparison of my black Australorp and the two chocolates.
Another option that I can ask is , how old are your hens?
I have had older hens that have not moulted and the plumage turns brown, then once they do moult, they regain beautiful beetle green feathers again. have they ever moulted?
