Good luck with it.
I was in your shoes a few years ago. My bees didn't end up making it though. They just dwindled in numbers until they had a total population that could fit in the palm of my hand. It ended shortly after that though.
Just an update:
This queen held on, I probably had 60 bees left taking care of her. About a month ago I gave her a frame of brood and eggs and shook an egg frame to add the nurse bees. They built up very nicely, she started laying eggs the very next day, after they released her from what turned out to be a protective ball of bees. I had put a news paper divider below the new frame but at the last minute before I closed it up she got above into the new bees. She continued to fill every void with eggs in that frame. 2 weeks ago, I split my main hive and put her in a large queen cage that I built and 3 days later they had totally accept her. I check her this weekend and she is laying solid brood patterns. She had one frame with a nice capped brood around the outside and a football size area in the middle that had every cell filled with eggs.
I left the OBH queen less and have been documenting what is happening. But that is for another thread.
