I know im abit late on giving advice on this game but just started playing it. Anyhow... these still go after dead fish and still lay eggs but the fish need to be in water. Ive been experimenting as i have just tamed my first along with my first ichthyornis.

Stand in water

Use hunt and retrieve on your ichthyornis

Get your Hesperornis to eat the fish and get golden eggs.

Saves swimming about everywhere trying to find fish then aiming at it to send your Hesperornis

Feed the babies fish. On The Island, use these as an Organic Polymer farm if you can't survive the cold long enough to get Kairiku (or are plain unlucky.)

There are a lot of these guys around cragg’s island.

Harvest them with sword for organic polymer.

What do golden eggs even do lol

Simple eggs when you cook them they are cooked to oil.. spend some time to figure out. Anyway, some gasoline to advance tech machinery

They are breedable. Why is no information about this

There eggs no longer produce extraordinary kibble so they are officialy a useless tame done waist your time.

Since these can drop Organic Polymer, you can kill them to get ahead and craft fabricated items far before you venture out into the snowy area with obsidian or the icebergs with penguins

Pain to tame

Just eat fish meat, so u need fish meat on ur feeding through

Slow

Not even ridable

The only good thing of this brid is that its egg

Holy crabs it took me two hours with a friend to tame but it turns out the thing does like a hundred thousand damage to all fish ( otters do it too)

Farm them for polymer also cuz they kill Kaikru the penguin!!!!!!!!!

Maewings cannot pick them up as babies. Nursing mode still works. Possibly a bug

When they lay an egg pretty much oil also comes out💀 it can be made into gasoline

Very good way to get organic polymer in the early game, since they spawn in south a lot.

Must tame for the switch. Make those kentro kibbles to tame yuty with their golden eggs. 25 fish for it to lay a golden egg. Count it out, then toss on land.

If you ever see this big duck, kill it and eat it’s natural polymer that will make you immortal for one minute

How to feed golden egg to Dilo on Ark mobile. This hesperornis has been a huge headache and my golden egg is about to spoil.

Why do we need these it’s just doesn’t make sence

Good for farming meat.

This is a helpful tip

It's basically just an alternative to organic polymer if you're too lazy to go to the Snow biome. The Golden eggs are irrelevant due to the fact that deinosuchus and Yutyrannus eggs can be used to make extraordinary kibble.
