Just to offer a different experience, we've kept chooks for years and it's been great. However, we do have a large yard where they are free to range around – I think this is key. In my experience there is no need to kill a chook after 3 years. Average lifespan for a chick is 8-10 years. Egg laying frequency does decrease with age, but there's no need to kill them just because they're slowing down a bit. Our oldest ch…
there is absolutely a reason to kill your chickens that aren't laying - it costs money to feed them. if you don't optimize for price by slaughtering your older hens you will easily be paying > $10 a dozen for eggs. all bets are off though if you consider chickens pets, instead of livestock. basic economics for me: 20 chickens, a dozen eggs a day, 30 dozen eggs a month. decent non-organic feed is $20 a bag, organic is…
1. Scale also comes into play: We only have 8 hens, and are able to significantly supplement their feed with scraps from the kitchen, which are effectively free. The chooks are free ranging over a similar area (~half an acre), so the lower density means more free-range food for them, I guess. As a result, our feed costs per egg are actually much lower than if we had more chooks, and keeping a few old hens around is a negligible cost for us.
2. We regard our chooks somewhere halfway between pets and livestock - it's not a binary choice. We enjoy having them around so they have some intrinsic value for us, but at the same time if they were getting too expensive to keep, we'd be OK with occasionally cooking one up.
