First things first, I have about 50 chickens now. 14 laying. They started laying around spring last year (I'm in Australia so about september/October) we started with one egg and had another chicken join in laying every 1-2 days so in no time we were getting a dozen eggs every day. Now, This started MONTHS ago. so far back I can't even remember now what happened, all i know is that we are getting TWO eggs a day for the past 5-6 months. and now this past week we haven't had any. I know chickens stop laying when they moult and my chickens have moulted. they started moulting quite a while after they stopped laying and they finished moulting ages ago with only one chicken left looking scrageldy now. They all look reasonably happy and healthy. what could this possibly be.
