You are definitely missing the point. Allow me to try again.
Just because someone disagrees with you doesn't mean they are missing the point.
Instead of trying to add calcium (even though that is popular, does not make it wise at all), focus on reducing (plant) toxins that interfere with the uptake of the calcium already present in the diet.
It's popular because it works. My vet completely agrees with adding small amounts of calcium via eggshells, cuttlebone or oyster shells. I believe you are confusing these things with liquid calcium which is a totally different thing.
Further, avoid giving parrots grit.
You do know that grit is not the same thing as a cuttlebone or oyster shells, correct? I have both soft bills as well as parrots, and my soft bills require grit as well as oyster shells. Grit looks like small chips of rocks.
I'm confused as to why you keep mentioning grit when I see no one disagreeing with you on that.
Perhaps this seems sage, but it is a meaningless statement.
This is only your opinion. Just because someone disagrees with you doesn't make their statement meaningless.
I think it's a pretty meaningful statement that I thought everyone knew. Birds are not humans.
When you can show me a human study that includes parrots, I'll read it. Otherwise, it's just information that is important for humans. It doesn't mean it that one should apply it regarding parrots.
Mice are not humans, but most good research for humans begins on mice. The physiology between parrots and humans has more similarities than differences. Sadly, parrot-specific research is highly lacking.
Parrots are also not mice, nor have I ever heard of them being used as research animals for humans.
I have been calm the entire time, but I appreciate the concern.
The fact that the another member felt the need to apologize for stating a commonly known and well-respected approach in the parrot world shouldn't ever have to happen.
I find it telling that you immediately assumed that they were talking about you remaining calm.
The only worse is doling out the same old bad advise ad nauseum and ganging up on anyone who brings fresh insight. I hear an echo in the chamber.
I see no one ganging up on you. When added together, our members literally have hundreds of years of experience with parrots. They share that experience when they post, and just because most of us may agree on certain subjects doesn't make it an echo chamber. Old advice doesn't necessarily mean bad advice.
When people with experience respond to you, you seem to have the habit of shutting them down, sometimes in a very condescending way.
It's difficult to have a conversation with someone who only listens to themselves, and who considers others' opinions meaningless.
I love your enthusiasm about parrots welfare, and I know you have things to share that could help others.
"You get more flies with honey than with vinegar" is a good thing to keep in mind when posting if you want to get your point across.
