Stardew Valley Egg Incubator: How To Hatch And Raise Eggs

Getting an egg incubator in Stardew Valley is a milestone for any livestock farmer. It lets you hatch your own chicks, ducks, dinosaurs, and ostriches without buying them from Marnie. The competitor page on this topic is an absolute mess of AI-generated gibberish—hallucinating "six-star ratings" that don't exist, claiming eggs take eight days for every species (it's actually three to eighteen depending on the animal), and rambling about non-existent features like "euro brewery salmon."

Let's clear the noise and look at how the egg incubator actually works, how to unlock it, and how to hatch every type of egg efficiently.

How to Get the Egg Incubator

You don't craft the egg incubator yourself; it comes built-in when you upgrade your farm buildings.

• Big Coop Upgrade: Upgrading a basic Coop to a Big Coop costs 10,000 gold, 400 wood, and 150 stone at Robin's carpenter shop. This upgrade adds a single incubator to the top-left corner of the building interior, allowing you to hatch chicken and duck eggs.
• Deluxe Coop Upgrade: Upgrading to a Deluxe Coop costs 20,000 gold, 500 wood, and 200 stone. Along with housing rabbits and pigs, this coop includes an automatic feeding system and an incubator.
• Ostrich Incubator: This is a separate item acquired as a reward from Professor Snail after completing the Island Field Office collection or from the Volcano Dungeon. It can be placed anywhere (indoors or outdoors) to hatch ostrich eggs.

Step-by-Step Guide to Hatching Eggs

Placing an egg in the incubator is straightforward, but a few specific game mechanics determine success.

1. Collect an egg from your coop or forage for a special egg (like a Dinosaur Egg or Ostrich Egg).
2. Walk up to the incubator inside your coop.
3. Interact with the incubator while holding the egg in your active inventory slot to place it inside.
4. Wait for the incubation timer to complete.
5. Ensure your coop has an empty animal slot available. If your coop is completely full (e.g., 4 animals in a basic Coop, 8 in a Big Coop, or 12 in a Deluxe Coop), the egg will finish incubating, but the chick won't hatch until you sell, move, or make room for the new animal.

Once hatched, you'll be prompted to name your new newborn animal. It takes several days of feeding and petting for the baby animal to mature and start producing items.

Incubation Times by Egg Type

Different eggs require different amounts of in-game time to hatch. Here is how long you'll wait for each species according to official game data from the Stardew Valley Wiki:

• White and Brown Chicken Eggs: 9,000 game minutes (roughly 3 in-game days).
• Void Eggs: 9,000 game minutes (approx. 3 days) to hatch a Void Chicken.
• Duck Eggs: 9,000 game minutes (approx. 3 days) to hatch a duck.
• Dinosaur Eggs: 18,000 game minutes (approx. 6 days) to hatch a dinosaur.
• Ostrich Eggs (Ostrich Incubator): 15,000 game minutes (approx. 5 days) to hatch an ostrich.
• Golden Eggs: 9,000 game minutes (approx. 3 days) to hatch a Golden Chicken.

Note: Void eggs hatched in a standard coop produce Void Chickens, while Dinosaur eggs produce small dinosaurs that periodically drop more Dinosaur Eggs instead of milk or wool.

Common Mistakes to Avoid

Farmers often run into simple roadblocks when dealing with incubation. Keep these points in mind to avoid frustration:

• Don't put incubated eggs in the shipping bin: It's easy to accidentally click the shipping box when clearing your inventory. Store rare eggs in a chest near your incubator until you're ready to use them.
• Check your coop capacity: If your building is maxed out on animal capacity, the incubator will stall or fail to yield a newborn animal. Always check your building stats from the menu at Robin's shop.
• Mayonnaise machine vs. incubator: Don't put rare eggs like Dinosaur or Ostrich eggs into the mayonnaise machine unless you already have a mature animal producing them regularly. Always hatch your first found rare egg first.

Frequently Asked Questions

Can I hatch eggs inside a normal shed or farmhouse?

No. Standard chicken, duck, void, and dinosaur eggs must be incubated inside a Big or Deluxe Coop equipped with the built-in incubator. Only the Ostrich Incubator can be placed outside of a coop.

Why won't my dinosaur egg hatch?

Make sure you placed it in the incubator inside a Big or Deluxe Coop, not on the floor or in a chest. Also, verify that your coop has space for a new animal.

Do higher quality eggs hatch faster or produce better animals?

No. Egg quality (silver, gold, iridium) has no effect on the hatching time or the quality of the adult animal. Any normal or high-quality egg works the same way in the incubator.

How do I get a Void Egg to put in the incubator?

You can acquire a Void Egg by having a Witch random event visit your coop at night, by purchasing one from the Krobus shop in the sewers, or by getting dropped by a Serpent in Skull Cavern if you have a specific setup.
