one can forever argue why events happened the way they did in AvP. truthfully, not much is really known about the amount of time passed from when the facehugger took a host, to the time the xeno bursts thru the chest. then again, as you say, the queen was under control , anything could have been used on her. my two cents are nothing was injected into her, those are the normal drones and enuff time had passed for their gestation. but thats just me bud.
