This sounds like a great compromise.This is what we talked about doing. Starting a new flock of 12 every year until the oldest is 3, then take them for processing. Essentially a constant cycle of eggs and meat. Part of our discussion is allowing me to keep my own flock on the side of 12 or so to do with what I want. A hobby flock, kept for no particular reason other than i raised them and want to let them live out their life.
I wanted to suggest perhaps your husband would be open to you choosing a few hens that stay and grow old with the flock in order to teach the young ones.
I like having older birds in my flock because they show the younger ones what things are good food, what to be afraid of, and what things they don’t need to be afraid of (the lawn mower, etc).
I haven’t had chickens long enough for them to slow down the egg production yet but we did process a couple of extra cockerels.
That was an unpleasant experience because DH chose to gut the birds before plucking them

Thankfully we have discovered a processor nearby that will slaughter, butcher and package our birds for $4 a piece which I’m willing to pay for if I don’t have to do it myself.
I have found that I have more of an emotional attachment to my birds than I thought I would.
Especially the ones I raise myself.
I also like to play with breeding and genetics so I’m not sure what we’ll do when egg production slows down.
Hopefully I can find some of them homes.
