Disclaimer: if you are on any other platform besides old mobile then ignore this tip.
On old mobile these things are neutral to all tames, meaning that if you try to lure a wild rex to a rando's base to be evil and they have all their tames set to passive, then that's not gonna do anything unless you manually aggro the rex onto you then tank each hit with your tame and the dude's tames in the rex's hitbox until something dies.
This also means that if a rex is near your base it won't be a huge problem until it is practically walking on your tames and your structures, in which you will have to kill it before it gets aggroed on you then starts attacking things in its way.
This also applies to gigas
However if you try this on any other platform including ark use you and your tame will get chomped up as wild rexes are aggressive to all tames.
From my experience my rexes have layed a bunch of eggs I have 2 females and 2 males and I was able to get 120 eggs in the past 2 weeks however you may not have the same luck, however taming 3-4 females and a male should enough to supply you with plenty of red eggs to tame quetzals and plesiosaurs
If you want to tame a breeding pair don’t just tame every single Rex until you get a female because you just need to breed one male and a female and if the baby is female just wait for it to grow up and build an army every female you get as a baby will be able to breed just use feeding trhoungs and it will be easy to raise them(if you need any ancient amber go around looting drops and you get get a lot I got 38 ancient amber in an hour
Tame a high level male and a high level female and start breeding: it's a bit cruel but I suggest you to claim only the baby females and kill the males for xp, keeping the females will speed up the breeding process because the cooldown to mate is only on females and not males
