The gameplay would be greater if Dinosaurs made nests wherever they feel comfortable to sleep and that's where they'll go when they take naps instead of napping on the ground because they look like they're dead. And wherever the herd/pack leader places its nest, the rest of the herd/pack places their nest near that nest.
As of Breeding, what if two dinosaurs of the same species could breed and lay their eggs on the nests. And to balance the game, other dinosaurs can run over it accidentally and break them and a dinosaur can only lay one egg at a time. The dinosaur that does hatch will have the same skin pattern as the mother, will have no genetic modification, and will be baby size. As that baby ages, it will grow in size.
Now gor the aging, what if the dinosaur size depended on its current age? I know what your thinking "Now that would mean all the dinosaurs released from the hatchery would be babies". To balance the game, depending on how long you leave the completely incubated dinosaur in the hatchery, like if you leave it in there for one minute (It depends on what frontier wants), then the dinosaur's size will be a fully grown dinosaur but will not affect the age. If you release it immediately then it would be a baby. As the baby ages, it will grow in size.
