IIRC from the book they engineered the original set of dinosaurs so they couldn’t produce the amino acid lysine and would (so they expected) require lysine supplements in their diet or they would die.
Then the dino’s escape and woops it turns it they can just eat chickens to get their lysine and it isn’t an issue for them.
They do mention the lysine contingency in the movie as well, thought it’s only a line or two and is likely easily missed by folks who haven’t read the explanation given in the book

Also, aren’t they all female? I know life, huh, finds a way, but this doesn’t seem plausible.
