Breeding is a new feature in Jurassic World Evolution 3. You can let breeding happen naturally or take full control through structured breeding programs. Each species has unique nesting habits and environmental needs, so managing comfort, space, and care is key to successful breeding. Understanding how breeding works will help you grow a healthy and thriving park. In this guide, we have provided the Complete Breeding Guide for Jurassic World Evolution 3.
Breeding in Jurassic World Evolution 3
Breeding in Jurassic World Evolution 3 can happen naturally or through special breeding programs. Each species likes different types of nesting spots; some like quiet, hidden areas, while others want to stay close to each other for safety. You need to send out your Ranger Teams to check on dinosaurs and see what they like.
How to Get Male Dinosaurs
Male dinosaurs are harder to come by than females, but there are several ways to get them. You can find wild males:
- Near your park
- Buy them from the marketplace once it’s unlocked
- Create them yourself through fossil synthesis
To synthesise a dinosaur, build a Hatchery and send your Scientists on Expeditions to collect fossils. The more fossils you study, the more control you will have over a species’ traits.
Preparing Nests for Baby Dinosaurs
Before hatching new eggs, make sure the enclosure is ready for baby dinosaurs. Young dinosaurs need more care. Check that there’s enough space for them to grow. After they hatch, check that the enclosure has enough plants, water, and shelter, and send the medical team to check for any diseases. You need to have Maintenance and Ranger Posts covering key areas. Upgrading the fences can also prevent damage to the baby dinosaurs.
Dinosaurs won’t breed if they’re not happy or uncomfortable. You can check their fertility levels by selecting them and clicking the eggs icon. This shows their current breeding chance, any fertility modifiers, and how it changes as they age. If fertility is low, make sure their enclosure meets all their needs; they might be sick, too uncomfortable, or unhappy. You can also give certain dinosaurs contraceptives if you want to stop breeding or control which traits get passed down.
Structured Breeding Programs
Structured breeding programs let you choose a male and female pair manually, giving you control over which traits get passed on. To get specific traits, synthesise dinosaurs in the Hatchery first. As you collect more fossils and understand their DNA better, you will unlock more customisation options.
You can adjust their colours, patterns, and change their stats. Once your genetically modified dinosaurs grow up, you can include them in structured breeding programs to pass down their custom traits. Combining both natural and synthetic breeding gives you the best results.
