Should I post videos as collaborations with my second channel?
So I have been posting on my Youtube channel for 3 years. It's been a slow and steady growth to ~4K subscribers. My content exists in this one type of niche category (don't want to get too specific), but I randomly decided to also post a video essay related to my niche and it unexpectedly blew up to be my most viewed video (almost doubled my previously most popular video).
This was a welcome surprise, and I do plan on making more video essays but they will be fewer and further between. In order to not alienate those who followed for video essays and not my other content, I decided to create another video essay-focused channel and mark that video as a collaboration. That has gained this second channel a couple dozen subscribers.
I'm working on my next video essay and want to ask if it makes sense to post it from the second channel and mark my OG channel as a collaborator or post it again from my OG channel and simply make my second channel a collaborator. I'm thinking the former to build up the second channel for those who are interested, but I wanted to check to see if there are any negatives of that approach.
Main concern is that my OG channel is monetized, and I haven't been able to figure out what the monetization impact will be if I post from the non-monetized channel.
