You are able to use the bison milk as a substitute for the wyvern milk

Easier way than milk:

My bf and I decided 2 days into the server we were gon yoink an egg with low pteras, so we did, 3 players dead 10 times, 3 pteras dead. But got a 45 egg, so worth it... We werent gon deal with wyverns for a bit so we straight up yoinked a snow owl, lvl 150. Cranked its stamina up to 4k. And every 10 to 20 min u go heal the wyvern after it hatched. You must just be very responsible and not forget abt it. 1k health drains in 30 min so u gon have to be quite active, once it reaches full maturity it can eat normal meat. I wouldnt recommend a deaodon, considering they munch food like crazy and if they run out of 20k food in 2 hours ur wyvern will most likely be toast when u wake up, just keep cryoing the wyvern when u cant check it. Then take it out when u ready to raise it with owl.

🐲 Basics of Wyvern Raising

Wyverns in Ark can’t be fed like normal dinos while growing — they require Wyvern Milk until they reach adulthood.

Key Timings Depend On:

• Maturation Time (Total time to become an adult)

• Baby Food Drain Rate

• Food Value of Wyvern Milk

• Server settings (e.g., maturation speed and food drain multipliers)

⸻

🕒 1. Base Maturation Time

In official rates on Ark: Survival Ascended:

• Wyvern total maturation time: ~3 days, 20 hours (~92 hours total)

• At 100% maturation, the phases break down to:

• Baby: 0% – 10% (first ~9.2 hours)

• Juvenile: 10% – 50%

• Adolescent: 50% – 100%

These times are faster on boosted servers (e.g., 2x maturation = ~46 hours total).

⸻

🍼 2. Wyvern Milk Feeding Details

• One Wyvern Milk restores 1200 food.

• Wyvern babies have around 350 food when born (varies by type/level).

• Food drains at around 0.1 food per second on official rates.

🧮 Feeding Interval Calculation

Formula:

Time Between Feedings = (Food Value of Milk) / (Food Drain per Second)

Example:

1200 food / 0.1 per second = 12,000 seconds ≈ 3.33 hours

✅ So, you should feed your baby Wyvern every 3–3.5 hours on official settings.

⸻

⚠️ Tips to Manage Feeding

• Milk spoils in 3 hours unless refrigerated or in a preserving bin.

• You can cryopod the Wyvern to pause food drain (great when offline).

• Starve-timing works: Let food drop to ~0 before feeding to avoid waste.

• Always have 1–2 spare milks for emergencies or server lag.

⸻

🔄 Adjusting for Custom Server Settings

If your server has a different maturation or food drain rate, plug those into the equation:

Feeding Interval = (Milk Food Value) / (Food Drain per Sec * Drain Multiplier)

You can use online calculators like Dododex or ARK Smart Breeding for tailored data.

🧠 Summary

Aspect Official Values

Total Maturation ~92 hours

Baby Phase Duration ~9 hours

Food Drain Rate 0.1 per second

Wyvern Milk Food 1200 per milk

Time Between Feedings ~3.3 hours

Feed every 3–4 hours during the baby stage, keep milk cold, and monitor food closely. Let me know if you’re on custom rates, Travis, and I can calculate exact feeding times.

ASA - Bison milk lasts 4 days in an ice wyverns inventory. Just leave a couple in it's inventory and you're good to go.

To know how much time need to the next feeding just do the next. Look the Food number# then that number multiply x 10, then divide /3600 and the result will be the number of hours until the next time need to be fed. F.E the food number is 1850.5 1859.5x10=18595 /3600 = 5.1 hours

Fun facts if you want to know more about wyverns!

-There are 4 types: Fire, Lightning, Poison, and Ice.

-Each wyvern has different uses, for example poison wyverns are good for pvp, and lightning wyverns have the highest damage output.

-To tame one you must steal an egg from one and raise it as your own.

-Baby wyverns only eat wyvern milk, which is obtained from kncoking out female wyverns or killing alpha wyverns.

-Wyverns do not spawn on every map. They spawn on maps such as Scorched Earth, Ragnorok, and Fjordur.

That's all!

PSA: Wyvern is pronounced “why-vern” not “wi-vern”

I feel i misunderstood and said that Poison got 14% buff on the spit, but now i think it's a nerf, sorry guys and girls.
