Calling for help from Australorp (hatchery birds) people! Do Australorps burn out in a year to 18 months or are they starting into a molt? We got our Aussies back in the spring of last year. They started laying around 21 weeks and laid an average of 5 eggs a week per bird up until a month ago. We now are getting maybe an egg a day from our 6 Aussies combined and sometimes we find an egg on the poop board(sometimes a shell-less one). Our new girls(3 Speckled Sussex,2 Welsumers and 2 Buff Bramhas) have been laying 8 weeks now and are giving an average of 5 eggs a day combined. They all are eating Layena crumbles free-choice and free-ranging in the backyard most every day and get limited treats. The Australorps are looking really ratty and dull and have never gone through a full molt. So.....do they burn out this quick,are they starting to molt or is there maybe some other problem we've overlooked? I will say the Layena crumbles,which has worked well for us for a long time,now seems to have an excess of dust in it(maybe5-10 pounds per bag)and we are beginning to question the quality but this springs additions to the flock are all fat,sassy and shiny. Any thoughts or similar experiences anyone?
