I have started writing a fiction book about dinosaurs. The first chapter is about a T rex pack with a mysterious egg in their nest. The pack itself has 1 adult female, 1 adult male, and 3 juveniles. The adult female was about to lay her eggs when she said "Oh my god, there is an egg in our nest that isn't from a T rex." The adult male said "What? That doesn't make any sense." The juveniles said "A mystery, cool." The adult male said "Yep. It's a mystery all right and we have to solve it. Okay juveniles, this is your mission. 1 of you is going to stay near the nest and protect it after your mom lays her eggs. The other 2 are going to search for dinosaurs that might have laid the mysterious egg. Got it?" The juveniles said "Got it" and started to investigate. Now here is where I start asking questions: 1) Since they are solving the mystery, there is a low chance of eating the egg. But what if it were to hatch? Would the T rex pack eat the hatchling or not? Now I know this depends on whether or not it is a carnivore and whether or not when it was bigger it could take down T rex. But would there be a higher chance of eating the hatchling if it were to hatch in the T rex nest? 2) If the hatchling were to be eaten, I think it would most likely be the adult female since she has to recuperate from laying those eggs. Would it? 3) How could the 2 juvenile T rex that are investigating not scare away any herbivorous dinosaurs or be eaten by carnivorous dinosaurs and still figure out what dinosaur laid the egg in the T rex nest? 4) If the eggs happen to get cold, how would a juvenile T rex warm them up without breaking? I mean the shells of dinosaur eggs are brittle, not strong like some bird eggs.
