Does the presence of queen cups support a swarming enviroment in the hive & should queen cups be removed or left alone & is it normal for bees to put Royal Jelly in a queen cup as a preparation "in-case" it is needed?

Also, should queen cells be destroyed during inspections?

A Beekeeper once told me to remove them during inspections after confirming the presence of the queen. But its starting to seem like that doesnt add up based on a few questions I've been asking... Please, let's hear some opinions!

Thanks Everyone
