Death is certain for us all. For some it comes sooner than for others.
It's both and both can be adjusted in some circumstances. I don't have those circumstances at the field.
I could have built a coop and run at the other end of the field and got Dig a couple of hens. Dig and Henry once out of their runs would no doubt fight. However, I've done this split (Father and Son) a few times in the past and given the space they work it out. It's not just about the hens. Chickens are territorial.
I wouldn't get an agreement to build another coop and run.
I have questioned this a few times in this thread.
I don't have any fundamental objection to eating the females or the males. I haven't since childhood. Keeping a closed flock and letting them breed has always seemed preferable and in the long run more successful than getting new hens or roosters in as required. Those one cannot keep, one eats. I've kept chickens like this until I took on the chickens at the field.
I have rehomed in the past, usually a pair or trio and I've known where they were going and the conditions they would live in. They mostly went to farms who kept chickens in much the same way as I did.
It's not like that here in Bristol.
Even in the best of keeping circumstances unless one is going to confine the males the ratio that I've found works best is three hens to one rooster.
The hens seem to prefer this ratio as well as the roosters. A good rooster can do all the things good roosters do when able to do it with three hens and, in the event one dies and the other is sitting for example, he is not left with no hens to boss about.

and won't pester another roosters hens.
To keep a closed flock going one needs to hatch chicks and 50%, over time, are going to be male.
Whether I'm right in wishing to keep the tribe going rather than calling it a day when Henry dies is debatable. It's important to me partly because the field has a history of chickens and to the best of my knowledge always with roosters. The field has the right by the terms of the lease to keep livestock. I have mentioned before that the field is leased as an agricultural holding/farm. That is almost unheard of in what is an urban area. Some members do not appreciate the worth of such a lease. I imagine, when I can no longer take care of the geese and the chickens the members will stop keeping them.
I don't know if I'm doing the right thing or the wrong thing; I'm doing what I know.
