[Alien Series]Shouldn't the Xenomorph Queen give birth to a baby(chestburster)queen, instead of a royal facehugger?

Through out the alien series, all the xenomorph queens look almost exactly alike, excluding the one from Alien Resurrection(which was cloned from Ripley). It is shown in the films that the only way a queen is created is by a royal face hugger impregnating a host.

 All these xenomorph queens definitely did not come from from the same host, yet, they all look the same. It would make more sense that Queens directly gave birth to another future queen, while also producing face huggers for creating drones and warriors. 

Xenomorphs that use humans as host resemble the body shape of a human, however, the queen has an all together different, more dinosaur like, body shape. This led me to believe that maybe the xenomorph queens were their own breed and that it would make more sense that the queens directly gave birth to a queen chesburster. 

Using a royal face hugger to create a new queen could also create lots more obstacles for the queen, as seen in Alien 3. It is also possible that the host could also be a bad host and will create a faulty queen.

The creation of a xenomorph queen is of vital importance to the creation of a whole hive. I think it would make more sense that that Queen should give birth directly to a new heir so it will be a controlled system and it can easily receive protection from the previous queen until it grows up.

What are your thoughts on this? It seems that for a queen, genetic variation does not matter. Please tell me if I am missing any facts.

Royal Facehuggers have a more stable genome that does not react to the host. 

Normal Facehuggers produce Xenomorph Drones, who are responsible for acquiring prey and protecting the Hive. It is advantageous for the Hive that these drones be well adapted to the environments that the Hive develops in, and as such the gestation in a host assimilates some of their genetic characteristics to allow for better adaptation. This is why the host of a Chestburster influences the end result of the Xenomorph Drone life cycle. 

The Royal Facehuggers, on the other hand, are intended to produce a Queen. Queens do not need to be as responsive to their local environments, because the Drones serve as their suppliers and protectors, allowing them to exist in relatively static conditions. Thus, they produce an Egg/Facehugger/Chestburster with a more stable genome, to produce a new Queen. They all appear the same because they are, for lack of a better description, pure-strain Xenomorphs. 

As for why they don't just give birth to a live Queen... They can't. They have the biological apparatus to lay eggs, not give birth directly, and they aren't able to control their genetics in such a way as to allow that kind of directed development. Certain gametes produce Drones, and when the Hive reaches a particular population density (likely triggered by certain pheromone concenrations) the queen automatically produces one or more Royal Eggs to allow for expansion of the colony.
