Before now, I've always let my hens live out their "natural" lives, but as I've always kept laying hybrids (except the aforementioned pigahlet, who was a cuckoo maran, who, after a few months stopped laying and started crowing, and had a chronic sinus problem, which didn't normally affect her, apart from an occasional honk!). And yes, I have always got attached to them, but! In all the years I've had hens, only ONE hen has ever just died by herself! i.e., without having to be culled because she was ill. She died of a heart attack at 2 1/2. Several have developed peritonitis, one (something I only ever came across once, thankfully), the first time she laid an egg, she lost the use of both legs for 24 hours. Totally paralysed. I had put her in a box, meaning to cull her in the evening, but once she laid the egg, she started to recover, although she was left with a limp! She lived to be 4 1/2, but every time she came back into lay, she lost the use of one leg again, and each time, it got worse and took longer for her to recover. Finally, she just didn't recover. I gave her a week, and she still couldn't put that leg under her. Very weird. She was also (although a laying hybrid) an inveterate broody! I've never raised chicks, and never had a cockerel, but that madam was turfed out of the nest box every hour, and I could have had a revolving door fitted to the sinbin!

And one girl, after about six months, never laid an egg that had a fully formed shell on it. That was so terribly hard on her, that she had to go. She was from the only batch of hens I ever got from a breeder (rather than a commercial supplier), and they all went down with respiratory problems within an hour of getting them home! They recovered with treatment, but only one of them really went on to thrive, and she lived to 5 1/2.
So, I think (hope!) that keeping them 18months/2 years will avoid a lot of the illnesses, and my son in law will do the culling for me now. At that age, you certainly wouldn't roast them, but they would be good for making chicken stock. And, if they are healthy when you despatch them, at least you
can eat them, whereas as it was, when I kept them for years, and they were then ill, you couldn't, and besides, by then, I was so attached to them, it would have been like eating the cat! :shock: And at least I will know that during their time here, those hennies will have had the best life a hen could possibly have, with more space than they could ever need! I'm getting six. The secure run would easily hold 20. The outside pen that the run opens into is 70 x 44ft.
