We're new to the backyard chicken adventure and currently have five chicks ranging from 5-6 weeks old. We are thinking about adding a few hens who are already laying and my wife has found three from an urban farm (we're in central Phoenix). One is an 8-month-old (Polish) and the other two are around 2-years old. In reading Storey's Guide, it seems that many people cull their layers after about two years of laying. Would we be buying hens just as they're dramatically slowing down their egg production, or would we still have a chance at getting several more years of good egg production? One of them is an Araucana and the other is a mix of Black Leghorn and something like a Jersey. We're still in negotiations about the whole "culling" thing at our home. Since eight hens is our practicable limit, I want to make sure most of them are decent layers and won't be facing butchering anytime soon (our focus is not the meat, but the eggs). Thanks - this forum has already been very helpful in helping us with our chicks!
