If you insist on taming one without an Ichthythornis, a good thing to be aware of is that the Hesperonis will sometimes be unable to eat a fish it kills, swimming back and forth to try and "find" it.

You can pick up a fish it's killed and feed it to it, and it counts for tame progress.

Also be aware that if you drop a fish you've killed, it can eat your fish off the floor and it will not give tame progress.

How to farm golden goose eggs:

1. Let your hesperornis harvest 5 coel, piranha, or salmon corpses using its dive attack (1)

2. Bring it on land so it can lay a normal egg (1)

3. Let your hesperornis harvest 5 coel, piranha, or salmon corpses using its dive attack (2)

4. Bring it on land so it can lay a normal egg (2)

5. Let your hesperornis harvest 5 coel, piranha, or salmon corpses using its dive attack (3)

6. Bring it on land so it can lay a normal egg (3)

7. Let your hesperornis harvest 5 coel, piranha, or salmon corpses using its dive attack again (4)

8. Bring it on land so it can lay a golden egg

9. Repeat the entire process for more golden eggs

Remember that this process requires no luck but purely work and perserverance

Great Tame. They lay special eggs which are used to make the best kibble in the game, extraordinary kibble. I found the best place to tame them is around the green obelisk. Follow the river out to the ocean and you should find some along the way. The river also has lots of Sabertooth Salmon and piranhas which the Hesperornis love. The process is still lengthy as they need lots of fish to tame, but finding those fish and paying attention to sizes (around 1.0 the larger the better) will make it much faster

Are you wanting to tame a hesperornis? Here’s how I tame mine! But first everything I say in my tips is of course what I recommend you can tackle this tame however you feel necessary! Also thanks for the support I appreciate it :D Alright now first will be your supplies to consider packing! Be sure to pack some decent armor, as the hesperornis spends most of its time in the water, this also means there will most likely be piranhas that will continually try to impede on your quest! Second on the shopping list is a trusty seagull, you may be wondering why, allow me to explain! So the icthyornis once tamed, has the ability to “hunt and retrieve” enable that option, set it on attack target, and tell it to attack a fish, it will then kill the fish, give it a golden fish buff, as well as bringing it back to you, phew the endless swimming for fish is over! Also as a added bonus the icthyornis’s golden fish buff will tame the hespornis way faster! So I would definitely consider taking one with you! Now that your good to go, it’s time to figure out where to find them! They spawn on every map, they will spawn anywhere that has fish, they also spawn in groups of 2/5 that I know of! Now that you have a vague idea on where to find them it’s time to start taming! Grab your icthy and tell it to murder a fish and bring it to you, once you grab a dead fish, line up your shot, then swim straight toward the duck and feed it, this way the fish never gets all up in your way when feeding, this takes a bit of practice so patience is key! Tell your icthy to fetch another fish… rinse and repeat! The process goes quicker with salmon! And eventually you got yourself a cute lil duck with a VERY aggressive attitude! What might this guy be used for? Good question! Allow me to explain! These guys are good for there egg laying capabilities, giving you one of two kibble to make! Ones I’m pretty sure basic kibble, the other one is exceptional kibble! And there’s nothing more fun than watching an army of ducks murdering your target, also a pretty quick fish meat gatherer! These guys are breedable, but do not lay golden eggs when bred! (They also make a cute little companion) Again thanks for the support, Good luck out there! :D
