Well, you know. The fact that she is a queen might explain the shape of the head (mostly).
And if a developing queen has this ability, it makes me wonder why in Resurrection the scientists were waiting for the queen to start laying eggs. I mean the method of the Predalien is far quicker and more effective, since it layed almost fully developed chestbursters than wait for the entire facehugger lifecycle to end.
And with the technology in that century, I doubt that they didn't found that she has this ability.
It was also safer for the scientist, because instead of having to carry all the eggs in the chambers where the future hosts were, they could have just locked them in the same room with the queen and let her to her job.
Not only that, but as seen in AvP-R she could put more than one chestburster inside the host. So instead of having 1 chestburster / egg, the scientists could have managed to create more.
I'm aware that A-R was launched long before AvP-R, but when you are doing something in a series, you mustn't ignore the continuity. And that's what they did.
I'm not nitpicking or anything, just curious.
