Three's a Crowd??? - Multiple Keikis on Rootless, Leafless Dendrobium Cane

[MauaMazuri]

Last year, I decided to start a more serious orchid collection after a decade of having a free phalaenopsis that was a table centerpiece at a conference and a several more recent additions of supermarket clearance mini phals and a Wilsonara. I had purchased a mystery grab bag of seedlings, which included a Dendrobium Burana Sapphire. Being new to dens, I read culture and care info that suggested den phals don't require a winter rest period. I did cut back back on watering a bit but apparently not enough for the temperature drop near my not well-insulated windows in my apartment. This led to some root rot that caused one of the canes to drop leaves and detach from the rest of the plant due to the loss of roots. This poor little cane had already started developing a keiki and appeared to have another bud growing farther up on the cane. I placed the cane upright on the surface of some sphagnum, which I mist whenever it's not quite dry. In the past month and a half, the keiki has gotten bigger and sprouted a new root, with two additional little bumps starting to form. The second bud/keiki hasn't grown too much - still barely a nubbin - so I assumed that whatever resources remaining in the detached cane were being diverted to the larger developing keiki. However, I just noticed a third bud/keiki forming. I'm worried about having too many keikis forming and depleting this very tiny rootless, leafless cane (only 2inches tall) before any single keiki can develop properly enough to be potted. What should I do if the other buds start turning into keikis? Should I remove the other 2 not-quite-yet keikis to allow the first one to grow stronger? Do I leave them all on there? Can the cane handle 2 but not 3 keikis? Advice would be much appreciated.

P.S. - The rest of the original plant is doing well with 1 new cane and another on its way.

First, Welcome!
A photo would really help. While some have said that you need to have 5 posts to upload a photo, I have seen others who managed to it right out of the gate. So give it a try. (from the Quick Reply" dialog box click "go advanced", then scroll down a bit to "manage attachments". You'll get a pop-up that lets you select the photo from your PC, then click Upload.
If that doesn't work a you can also put the photo on a service like Google Drive, and get a link which you can then insert in your reply.
