Same thing happened on my new hive this year. When placing my new queen cage in the hive, I left out one frame for a total of nine. Within a week, I had bridge comb and comb resembling a mushroom being built off the side of the one with the largest gap. The queen would hide under there until I removed those bridges and the mushroom. When I placed the tenth frame in, they proceeded to build normal comb, which made it easy to monitor their progress.

He had frame spacers in his honey supers, and inserted 9 frames of foundation. Rod Billett Lexington, SC
