Yes I have five Rhode Island Reds and four Dominiques. They are all hens. They reached adulthood this year, each bird lays an egg every 1-2 days.

So far we have only been doing the eggs but expect them to stop laying when they reach 3-4 years old. This is my first flock so I don't really know yet. I am not sure if I have the guts to prepare a bird for meat.

A while back I got to see my uncle prepare three chickens and a goose for thanksgiving dinner and it seemed like a rather straightforward process. Basically, after cutting the head off, the bird is dipped into boiling/scalding water briefly and then the feathers are plucked. I don't recall what they did with the innards, I may have stepped out for that part.

It's pretty easy if you use a traffic cone as a "killing cone" to stabilize the head you're cutting. Since they're so old you might as well remove only the digestive tract and boil the whole bodies into broth, cause the meat will be inedible.

If you have kids, they're typically not as grossed out as adults and it's a really good biology lesson

It's either you or the raccoons.

I’m totally fine eating meat, but readily admit that I could never actually butcher an animal (and I don’t think that’s inconsistent). Anyway, how long do hens live? Could you let them wander around as pets?

I have a hen that has lived at least 6 years. At least where I live, the issue is them being killed off, not dying naturally. Also, if you have a large enough yard, they can walk around freely, just remember that they will take a dump anywhere they like, and I don't believe there is any way to stop that.

My father used to keep one (as a pet), she lived 13 years which is I believe rather exceptional, the average being around 8 year (range 6-10 years).
