Re: To increase or not
Worried that might be a supercedure cell rather than a swarm cell. If they are trying to replace the existing queen best leave it. Swarm cells are more numerous. Given how far along the queen cell is in your pick and lack of others equally mature I'm leaning towards that being a supercerdure. With those cups built where they are might even be an emergency queen.
If you move it make sure there are eggs left behind so they can raise a new queen if needed.
Try living life with the attitude it's not about what you want to do but what you should do!
