Five species-named sky eggs come from Clara’s 20 Pufferfish → return → 70 Triassic Rocks → return → 10,000 Coins sequence. Quetzalcoatlus Egg has a reported 5% award chance; its hatch result is already named on the egg. Keep the 3 Dunkleosteus Eggs for Kai and 3 Sea Eggs for Yara unhatched. The dated Allosaurus, Velociraptor and Diplodocus code rewards are separate routes.
A quest hand-in is different from incubation. Kai’s reported 12 Dunkleosteus Shards produce the required batch of 3 eggs; do not multiply that batch into 36 shards. The Sea Egg article does not list every species or its individual shard recipe. Calculate missing quest materials.
For a fossil-made egg, return to Dr. Ivy at Home, choose Get Egg, then Visit the Incubator and Place the Egg. Wait for that egg’s warming period before hatching. After the hatch, place the newborn on the ranch and keep Belly above half while it grows. Food care belongs to the hatched animal, rather than the egg timer.
October 5 recorded egg
Duration
Name interpretation
First-play Cambrian example
5 minutes / 300 seconds
Hallucigenia, normalized unconfirmed from “hallucenia/hallucinia”
Following Devonian example
2 minutes 30 seconds / 150 seconds
Tiktaalik, normalized unconfirmed from “tick talic/ticktallic/Tectalic”
These are useful source-session examples, not every Cambrian or Devonian egg’s current timer. Jurassic Dinoz states the first warming duration at 6:05 and names the hatchling at 11:20; the second duration is stated at 20:12. The separate Ricoko ten-minute AFK wait is elapsed time in an epic-egg recording, not an exact universal hatch duration. Use the planner with a recorded preset or your actual egg duration.
Keep Kai and Yara’s eggs unhatched
Kai asks for three Dunkleosteus Eggs. One supplied quest batch uses twelve Dunkleosteus Shards from Devonian rocks with Silver or better, exchanged at Home. Give the three eggs to Kai without hatching them; choosing three output eggs does not make the input thirty-six shards.
Yara separately asks for three Sea Eggs of any kind. Their shards come from Panthalassa rocks using Titanium and are traded at Home’s Dr. Ivy. Leave those eggs unhatched too. The guide does not list every Sea Egg species recipe, and an already-hatched ranch animal is not described as an alternative hand-in.
For a fossil-made egg, complete its set and return to Dr. Ivy at Home. Get Egg leads to Visit the Incubator and Place the Egg. Code eggs are separately dated rewards; Clara gives a species-named Sky Egg after her registered loop. These are distinct routes, not one universal egg recipe. Keep Kai’s three Dunkleosteus Eggs and Yara’s three Sea Eggs unhatched.
Which Sky Egg is rarest, or worth repeating?
The flying guide calls Quetzalcoatlus fastest and rarest with a 5% award chance from Clara. The other four exact probabilities are not supplied, so a complete rarity tier list is unavailable. Each fresh repeat takes twenty Pufferfish, seventy Triassic Rocks and 10,000 Coins. An already-owned Adult flyer supplies the known travel role without buying another egg; a specific Quetz goal can use the conditional chance and workload model.
Do Incubator 5 or 6 make eggs hatch faster?
The official offers are Incubator 5 at 299 Robux and Incubator 6 at 399; those names do not state five/six extra slots or a speed effect. Skip Hatching Cutscene at 49 refers to the cutscene, not the warming wait. The October 5 examples of 300 and 150 seconds remain recorded timers, not a fastest-all-eggs schedule. Use your actual timer in the planner and compare the known paid labels separately from Coin egg payments.
Egg list, listing order and locations
This listing contains 10 entries, including five named Clara awards and the distinct Kai/Yara unhatched hand-ins. The cards show each entry’s useful collected fields, source/version conditions and real detail or next-step link. The listing order is a reference arrangement, not an income or rarity tier.
