I hear you. I hate butchering day too and so far I've only done quail.
But you know, good for you. By raising some of your own meat, you will reduce some of the factory meat farming that most of us rely on for meat. Those poor animals live miserable, painful, traumatic, horrific lives and at the end of it are probably relieved when the bullet hits their brain (or whichever method is used).
You've provided your babies with a happy, fulfilling, pleasant life and they have no idea it's "nearly time." They're taking life one delightful day at a time and when the time comes, it will be over so quickly they won't even realize anything happened.
And the truth is, you can't keep a group of polygynous pets (i.e., animals that live in groups of one boy to several girls) without being a party to the deaths of others. Nature provides boys & girls in a roughly 50/50 ratio and if you can't keep them all... something has to happen to the extras. At hatcheries, boys are either discarded at birth and turned into pet food, or in some breeds, raised to butchering age (usually more of those miserable, horrific battery lives) and slaughtered for the commercial market. In either case, when you buy that one male and six females, you are in essence agreeing to the deaths of five boys.
This is why I agree with my vegetarian friend that you can't be truly vegetarian for moral reasons unless you are vegan, because all animal products (even milk eggs) directly or indirectly involve the deliberate killing of animals.
I am not vegetarian, and that is why we try to raise some of our own meat. In fact, I am seeking homes for some extra males but in my heart I know the truly humane thing would be to slaughter them and use the meat. Because sending them to homes as a bachelor flock will mean consigning them to a life of celibacy and handing them over to someone who probably won't care for them as well as my birds are cared for. It seems to me it would be more humane to let them finish their days as happy members of their birthright flock on the property where they were raised. I just can't quite bring myself to do it...
But I admire you for following through, and you'll feel better about it afterward. It's a mark of our compassion when it is difficult every time--you don't ever want it to be easy. And you may not feel like eating the meat right away. That's okay. Let it sit and you'll want it eventually.
Don't forget to let it "age" in the fridge for a day or so before freezing...
