I tend to prefer a lighter hand when it comes to moderating, so I haven't stepped in... yet. But I am going to ask that a more laid back tone be adopted, here. The back and forth is getting a bit more animated than is really necessary.
Dave, Dani (SpiritSage) has given you her opinion on what should be done for your bird based on your description of his apparently frequent falls. Personally, I think it sound advice. Some birds are indeed clumsier than others, and it is possible that either too aggressive a nail clip or too long a set of nails could be responsible, but the fact is that it could also be a sign of illness of some sort. Even a neurological disorder. This is why she is as concerned as she is. She's just looking out for Maxx.
That said, I also realize that we are not onsite physically examining your bird. And that, of course, is the limitation of the internet as a diagnostic medium. Given that limitation, when someone tells you a set of symptoms that could be a sign of something serious, the best suggestion is to recommend a vet. If, however, you have experts on hand capable of diagnosing your ekkie in person, I'd say they have us at a marked disadvantage.
All we can do is give you advice based on our experiences. But it is for you to decide if said advice is right for you and for Maxx.
As for the possible dangers of microchipping, perhaps it is a rare event. But I'd rather know if it is a possibility, however remote, than be potentially - and tragically - surprised later on. You know what I mean?
Long story short, it's all love here, people. Let's keep it positive.
