^(nice banner by the way Rakai)
Rakai took the words right out of my mouth, but pretty much that what was in Prey, War, and Hunter's Planet.
As for females with offspring, they don't lay eggs like the Hish, they produce just like humans, and as a mother is very protective of her babies, the female Pred is no exception. Rather then the Hish which kill the weak spawnlings, a mother Yautja will fight to the death to protect her young.
I don't know if Yautja stay as couples, since in Hunter's Planet a Leader Pred name numerous female conquests, but it could be possible.
As for female size in the books and the comic AVP: Deadliest of Species, the female tend to be bigger. Though as far as movies we haven't seen a female yet to judge.
And they can change sexes and have sex as we do...Or is there something to prevent that?
In Prey, Hunter's Planet, and War AVP books prior to yours, the gender stay the same, no indictation of switching gender, females are females and males are males. both had similar attributes of their human counterparts.
It's possible you could go with the idea that Rakai and I talk about, since I heard something similar happen like in Star Trek.
one other thing is the Yautja have no Feral rage glands.
almost forgot the Yautja have an honor system during their hunts( the Hunt is the way of their life), like the movies gave hints to. Pretty much not hunting unarm opponents, children, women with child, but in the books there were clans mention not hunting any high intelligent life-form like humans.
