Last week was the week from chicken hades. I lost four chickens, due to various weird things. 1. One chick a day after hatch, most likely due to some congenital problem. 2. My beautiful splash Orpington because she suddenly got a prolapsed vent and the other chickens ripped her intestines out. I put her down. 3. One young Barnevelder who accidentally flew into the fence and broke her neck. 4. One one-eyed Barnevelder who suddenly went downhill because his equilibrium was thrown off. I put him down. Yeah, it was that kind of week. I popped 7 eggs in the incubator (third hatch) and wondered how often other folks go through turnover. This is the most I've seen in two years. It's disheartening, but at the same time, I'm looking forward to more autumn chicks. I figure I'll do another batch after this one and then wait for the springtime. I know that people have birds that can live 8 or more years, but is this typical? I have 10 of my original 15 going on 3 years old, but I have had attrition. Do all your birds live long, or do you have attrition too? Do you plan a certain number of new birds to handle the attrition?
