I just think that the grief comes with the amazing experience that birds are.
I absolutely agree. I have a Cockatoo that I have had him for years. He's family, If something happened to him, well, I just don't know how I'd handle it if we want to be totally honest. Here's hoping he outlives me, I don't want to find myself in that position, although the urge to kill him is pretty high on some days, like when he chews up shoes or something.
Back to the 'bashing' No, nobody is bashing you, but THAT is my point kind of, oh just never mind, it's not worth the time trying to explain.
As birds get older, ... think teen agers, and 20 somethings that know EVERYTHING, just ask them, they'll tell you. The same thing happens in a way, in the bird community too. Those cute fluffy fuzzy things that got along, now all of the sudden turn into teenagers, that the hormones are kicking in, suddenly want to kill each other and need their OWN SPACE, and in some breeds, LOTS of it too. So you wanted to butcher them, and were prepared to do so. Did you know how much room that dozen of them actually needed to keep them safe until they got to that age, or are you now finding out the hard way, that maybe you really only had room for one or two?
This isn't about your feelings, this is about what's best for your birds. Things can go bad quickly that can kill entire flocks off in a day or so. Yes they will end up dead when you butcher them but still, need to be kept healthy until they reach that point.
My unqualified opinion, take it or leave it as just that. You have too many birds, you probably don't have the room to house them properly. So, your options.
1. Cull some of them a bit sooner than you expected to.
2. Get more room for them (is this really feasible?)
3. Give some away, (Probably an easier option)
4. Hope they don't kill each other or get sick and die until the time when you kill them in the planned way.
I honestly don't see this problem getting better as time goes on, it's not one of those type of problems. You are probably going to have to make a decision here that you are not going to like.
