I have a lot of headcanons of Changelings. One of the most prevalent being that changelings don't actually have a Hive Mind, or a Queen Mind, but a strange hybrid between the two. All changelings are connected, and on a really basic level share everything. This allows them to talk telepathicly with each other anywhere on the planet. However the Queen would be able to over-power the changelings in her brood to force them to do what she wanted.
This is very similar to how it is set in Papi’s hive and canon. There is a hive mind which the Queen uses to keep track of her hive and coordinate them in case of emergency, but it does not interfere with a drone’s individuality or personality unless that is overridden by the Queen to keep the hive in order.
